Vent session. Where’s my baby

I just don’t get it. I’m 25, I have regular sex still no baby. It’s going on 4 months now and I know my fiancé is waiting too. I’m getting discouraged. Finally bought an ovulation kit and of course ovulation is low. I’ve already been tested for endo and PCOS, as well as an pelvic ultrasound and everything has come back normal even though my period is very irregular I have my first fertility appointment soon but man, I’m ready to post my positive pregnancy test 😭
