I've been trying for 9 months with my boyfriend and I'm still not getting anything we've had sex so many times I had it twice first time not sure how long and had it again for 2 or 3 months a lot of peopl say there's nothing to worry about unless u had it treated my boyfriend had it too before does it also affect fertility in men does it make them infertile? I just want my baby already 😔
