Can I have a baby?

My boyfriend and I have been together for almost 7 years. We’ve been together since I was 15, and he was 14. (We’re only nine months apart) for the first year and a half we had sex unprotectedly ALLL THE TIME (mind you we’re both teenagers). Thankfully I never had a pregnancy nor a pregnancy scare.

After the year and half of being dumbass horny teens I finally decided to go on birth control called Nexplanon aka the implant that goes in your arm. That lasted for three years than I decided to not go back on it but it made me crazy and gain a lot of weight, so once again we’re back to our pullout method. Once about a year we both decided we should try and yet still nothing, at first I thought “alright cool no pregnancy or a scare” but now that we’re actually trying I’m getting scared... anyone else experience similarities while trying for a baby? If so please let me know I’m going crazy 😭
