Maternity leave in the United States typically begins anywhere from a few days before your due date to the day you give birth, though some people start earlier if pregnancy complications arise or they use vacation time to ease the transition. There’s no single federal rule dictating exactly when you must start or stop your leave. The timing depends on your employer’s policy, whether you qualify for federal job protection, and whether your state offers a paid leave program.
When You Can Start Your Leave
Most people begin maternity leave either on their due date, when labor starts, or shortly before. Unlike some countries that mandate a set number of weeks before the birth, U.S. federal law doesn’t require you to begin leave at a specific point in pregnancy. Under the Family and Medical Leave Act (FMLA), your 12 weeks of job-protected leave can start whenever you need it for pregnancy-related incapacity, the birth itself, or bonding with your newborn.
In practice, this means you could start FMLA leave weeks before your due date if your doctor determines you’re unable to work due to pregnancy complications like preeclampsia, severe nausea, or bed rest. That time counts against your 12-week total. If your pregnancy is uncomplicated, many people work right up until labor begins and save the full 12 weeks for recovery and bonding afterward. Some use a mix of accrued vacation or sick days in the final week or two before the due date, then start FMLA leave once the baby arrives.
How Long Maternity Leave Lasts
The length of your leave depends on which protections and benefits apply to you. Here are the main sources of leave time:
- FMLA: 12 weeks of unpaid, job-protected leave per year. This is the federal baseline, but it’s unpaid and not everyone qualifies.
- Short-term disability insurance: If you have coverage through your employer or a state program, it typically pays a portion of your salary for six weeks after a vaginal delivery or eight weeks after a C-section. This covers the medical recovery period only.
- State paid family leave: Thirteen states and Washington, D.C. have programs offering at least six weeks of paid leave. Benefits vary by state, and four additional states are beginning benefit payments in 2026.
- Employer policy: Some companies offer their own paid parental leave on top of legal requirements, ranging from a few weeks to several months.
Many people layer these benefits together. For example, you might collect short-term disability pay for six or eight weeks of physical recovery, then switch to a state paid family leave program or use employer-provided parental leave for additional bonding time, all while FMLA protects your job for the full 12 weeks. The key is that these programs often run concurrently rather than stacking end to end. Your employer can count your disability leave and paid leave against your FMLA 12 weeks at the same time.
Who Qualifies for FMLA Protection
Not every worker is eligible for FMLA leave. To qualify, you must meet three conditions: you’ve worked for your employer for at least 12 months, you’ve logged at least 1,250 hours during the 12 months before your leave starts (roughly 24 hours per week), and your employer has at least 50 employees within a 75-mile radius of your worksite. Public agencies and public or private schools are covered regardless of employee count.
If you don’t meet these thresholds, you’re not entitled to federal job protection, though your state may have broader coverage. Several states extend leave rights to workers at smaller companies or with shorter tenure. Check your state’s labor department website to see what applies to you.
When to Notify Your Employer
For a planned maternity leave, federal law requires at least 30 days’ advance notice when possible. Since a due date is known well ahead of time, this is almost always achievable. You should follow your company’s standard process for requesting leave.
If something unexpected happens, like premature labor or a sudden complication that requires bed rest, you need to notify your employer as soon as it’s practical. Even in urgent situations, the Department of Labor expects you to give notice within whatever timeframe your employer normally requires for unplanned absences. In most workplaces, that means calling in the same day or the next business day.
Beyond the legal minimum, giving your manager and team more lead time, often around two to three months before your due date, helps with planning your workload coverage and makes the transition smoother for everyone.
Paid Leave Options
The federal government does not require employers to pay you during maternity leave. FMLA guarantees only that your job (or an equivalent position) will be waiting when you return. Actual income during leave comes from other sources.
Short-term disability insurance, if you have it, typically replaces 50% to 70% of your salary during the recovery period after birth. The standard coverage window is six weeks for a vaginal delivery and eight weeks for a C-section. Some policies include a waiting period of one to two weeks before benefits begin.
State paid family leave programs fill a bigger gap. These programs generally replace a percentage of your wages, often 60% to 90% depending on your income level, for a set number of weeks. States with fully operational programs include California, Colorado, Connecticut, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Washington, and Washington, D.C. Delaware, Maine, Maryland, and Minnesota are launching their benefit payments in 2026. If you live in one of these states, you may be able to combine disability benefits for the recovery period with paid family leave for bonding time afterward.
Planning Your Leave Timeline
A typical maternity leave timeline looks something like this. Around your second trimester, review your company’s parental leave policy and your short-term disability coverage. Check whether your state has a paid leave program and what its application process requires. Some state programs ask you to file a claim before your leave begins.
About two to three months before your due date, have a conversation with your manager and HR department. Confirm how many weeks of leave you plan to take, discuss how your responsibilities will be handled, and submit any required paperwork. The formal 30-day FMLA notice should go in writing around this time.
In your final weeks of work, tie up projects, document your ongoing tasks for whoever will cover them, and set up an out-of-office plan. If you want a buffer before the birth, consider using vacation days in the last week rather than dipping into your FMLA or disability time early.
After delivery, your disability coverage (if applicable) kicks in for the recovery period. Once that ends, any remaining FMLA time, state paid leave, or employer-provided parental leave carries you through the rest. Keep in mind that FMLA leave doesn’t have to be taken in one continuous block. If your employer agrees or if you have a medical need, you can sometimes take it intermittently, returning to work part-time before transitioning back to your full schedule.
