I'll be 39 in September. We've just started trying for our second. I'm still nursing my 27-month-old daughter. My cycles started in September and have been regular for the last 7 months. However, I read today that breastfeeding can impair the progesterone production which results in unsuccessful implantation, especially for older women. 😔 Anyone here who can tell me otherwise? Would love to hear about your experience.
