Hello all. I just ended my period on the 24th or 25th (got it on the 20th which was 5 days late!).. and I had sex with my boyfriend only once! since it ended (had sex on the 26th or 27th) and now on the 29th and then again today, I noticed when i wipe myslef i'm having light red spotting.. ONLY when I wipe myself (not even in my panties) Im also having lower stomach cramping and just feeling strange... I do have 1 son already whom is 16 months.. i got my first post partum period when he was 4 months old. ( i did have a lot of sex with my boyfriend in the months of febuary and january, but i did get my period last month on the 20th.. so i can't be pregnant right?)

what can this be?? this has never happend to me before!! help plz!
