8 CYCLES WITH AF. HELP PLEASE!!

Cassandra 🐟
It's been 8 months that I have been having my period every 28-30 days. I started in Nov without taking anything to regulate just on its own. I have been TTC for over 2 yrs now but the past 7 months I haven't been sexually active since my husband it's deployed. Is it PCOS what I have or is it normal? My OB doesn't believe in PCOS🙄😠 Has this have happened to any of you ladies?
