I was 16 when I had my first child but believe it or not my period came on regularly for 2 month I didn’t have any symptoms but one day I woke up in pain my stomach I try everything to make it go away my period just came off the school nurse made me an doctor appointment then boom they said congratulations ma’am you’re pregnant I was shocked. I asked how’s that possible if my af came last week they said I was experiencing IB but I wasn’t it was an regular af but anyways don’t give up hope ... it’s seems like it’s taking forever && the month you finally give up boom you’re pregnant
