I’m starting to feel like I can’t have another baby😓

I’m 32 years old ttc #2 for goin on 2 and a half years now and I feel like my period is so irregular that I am starting to give up hope! I bd all the time and I don’t even stress on it but it’s drawing closer and closer to the 3year mark. I don’t know what I should do to help this out? My period this past year has been at 3months then 4and a half months then regular for two months and now I believe I’m now 4months no period but don’t feel that any of the things I may concider to be pregnancy like symptoms can be dismissed as pms or me being old lmao. I’m afraid to take a test and be told the same as the last 4moth stint that I’m NOT pregnant... not sure what I should do?? Any suggestions or thoughts would be appreciated ❤️
