I have a 10 month old son (my 3rd child) who is still breastfeeding & i got my period last month & was due on Tuesday this week but no sign of it yet. Ive never had a regular cycle but the 'regular' in the sense that i get them anytime between 28-31days. I dont ovulate every month either but have had unprotected sex with my husband. Does it take a while for them to get back to normal?
