Breastfeeding & Your Cycle: What to Expect
Breastfeeding raises prolactin, the milk-making hormone, which suppresses ovulation and often delays your period, sometimes for many months. As feeds drop, especially at night or when you start weaning, prolactin falls and your cycle usually returns. Ovulation can restart quietly before your first period.
How nursing shapes your cycle
The more often and exclusively you nurse, the longer periods tend to stay away.
- Frequent, round-the-clock feeding keeps prolactin high and periods away.
- Dropping night feeds or introducing solids often triggers the cycle's return.
- Cycles may be irregular at first as ovulation restarts.
- Some spotting or a return of PMS can signal your cycle waking up.

Frequently asked questions
Does breastfeeding stop your period?
It often delays it. Exclusive, frequent breastfeeding keeps prolactin high enough to suppress ovulation for many women, so periods can stay away for months. This is not guaranteed contraception, though.
Will my milk supply drop when my period returns?
Some women notice a small, temporary dip in supply around their period due to hormone shifts, and milk can taste slightly different. It usually rebounds, and staying hydrated and nursing regularly helps.
