Hello ladies, and or gentlemen. I’m 18, and I had unprotected sex twice in the same day, he came in me both times, i had a miscarriage 10 months ago, but that was with a previous relationship. This guy and I have had sex multiples times unprotected and he has came in me. I can’t tell if he’s fertile. We had sex 2 days ago, but I don’t know if he’s fertile or not. If he is what’s the earliest I could have signs of pregnancy? My back is aching, I’ve had a headache for a day now, and nothing will help. I’ve also had good cravings. HELP ME!!!
