I have a 9 month old baby.I am breastfeeding, and no menst. Period yet. Last week had one day light, pinkish spotting. My boyfriend and I had sex the night before. Had negative. Pregnancy test, but am wondering if it is possible it was implantation spotting or just irritation from intercourse?:confused:

Maybe. You have had intercourse in the last nine months so there is a possibility.

I would suggest you go to the doc and get a blood test.

Please read this about implantation bleeding. But yes, it is possible to get pregnant while breastfeeding.
