I delivered my daughter vaginally on 11/28. I bled for 2 weeks after. Around 4 weeks pp I did have unprotected sex 2 times. Now at 6 weeks pp I thought I started my period, but it's really just been spotting of old and new blood. Only lasted 3 days. I am exclusively breast feeding. I just don't know if I should consider this my period, late bleeding or possible implantation bleeding? Any opinions are appreciated!
