I stopped breastfeeding 3-4 weeks ago (until my baby was 17 mos.) and still have not had a menstrual period. Additionally, I pumped 3 days/week + breastfed(...I work part-time) up until this time. We would like to try for another baby, but I am fairly certain that the odds of conceiving are low. Should I be worried? I have read that it can take some women as long as 2-3 years for the return of their menstrual cycle. We became pregnant very quickly with baby no. 1 and pregnancy/delivery were both uneventful.
When it comes to your cycle, 3 months are normally the time frame where you should see the effects of a change. If you do not see your first period in the next 3 months, speak to your doctor about it. They might try to jump start your cycle again. It is however unlikely that it will take that long.
