So im ttc...tmi

A year ago i went to the doctors for a irregular periods. So they put me on provera to regulate them. Then i got off the pill almost 2 months ago, which my doctor told me that every 3 months i would get my period. I had many vaginal ultrasounds, and the doctor said everything was fine i just have a tic tac size pulip. I have never missed my period so much i feel like it will be impossible for me to ttc. I have just been feeling like damn what if i can't have childeren ever. Any thoughts?
