If you look at my questions from like 9 months ago, i was pregnant, but unfortunately i had a miscarriage. D: I'm 13 and now i am 3 months pregnant, should i be happy or should i be scared. the doctors said they don't know the possibilities of me having another miscarriage? Me and Pedro (the dad) have been together for like a year too. also don't call me stupid. please. shh.
