So I've had about 7 sexual partners since I lost my virginity at 15. I'm 22 years old and have taken different types of b/c off and on. I've been "taking" yaz for about a year and have been dating my boyfriend for 3 years. With 5 different partners, including my current boyfriend, I've had unprotected/irresponsible sex. With my current, it's been unprotected more than 10 times. Twice while I was technically supposed to be fertile/ovulating. I would be ecstatic if we were to get pregnant soon, but there have been so many times where I feel I should've been pregnant! Does alcohol or smoking weed affect fertility? We both drink and my boyfriend smokes a lot. As someone who has always answered "a mom" when someone's asked "what do you want to be when you grow up", I would just die if I turn out to be infertile.
