Trying to conceive

Hello guys! Um I came on here today because I actually needed some advice. So I recently just turned 19 and I’ve been trying to get pregnant it’s been about 3 months of me actually trying. At 13 I was on the depo birth control n was on n off of it until I was 16 I had irregular periods but after about a year or so I’ve gotten back on track n haven’t taken any Contraceptives. In the back of my mind ... i keep thinking “what if i have fertility issues cause of the birth control” or like “what if my boyfriend has low sperm count” and it’s actually been really frustrating 😔 I’ve tried speaking to my gynecologist about it and i feel like she doesn’t take me serious. She handed me prenatals and told me to start taking them she didn’t talk to me about anything or give me any advice, so that’s actually why I came onto here hopefully someone could help me out on my journey 🥺❤️
