Not going to Give up, but maybe I need to see a fertility specialist... Me & my boyfriend have been having unprotected sex for 4 years. We used protection one Time. We always have sex after my period or my most fertile days, he always finishes in me & I have only been pregnant once & It Ended in a miscarriage that was 3 years ago. Is it him or is it me? he smokes a lot cigarettes & weed, I don't drink, smoke or anything like that, I exercise 15, 30 minutes a day but then again... Maybe I'm not meant to be a mother & it truly saddens me.😔
