Advice

Hello all. I'm new at this. My ex fiancé & I tried for a baby.. We had intercourse starting on the 1st, my ovulation on the 10th & we stopped on the 13th. We had sex every single day in hopes of getting pregnant. Well we had a miscarriage not to long ago. The whole situation is messed up. I got pregnant before & had some problems so we split, 3 weeks later back together again. Then a month after that we lost our baby. I was 12 weeks. Well now we tried even harder for a. Baby this month, well lookin here, he left again. I'm just scared that if I'm pregnant, the stress will cause me to miscarry. I just need some reassurance. &
Someone to talk to..
