Ladies I'm 12 days late , but I don't think I'm pregnant!I mean I did have birth control pill last month because my Bf came in me , but what else can be the reason? :(
I'm also getting cramps and all!Oh I also had discharge somewhere around the beginning of this month.I thought it was period but it did not even last a day!
