Out of wake period. I never know when I'm ovulating. Beyond frustrated.

I've been keeping track of my periods for years. I keep ended up with hormone embalances all the time. I either don't have enough estrogen or enough anything.  My periods are so weird I cannot tell when I'm going to ovulate. I'm always late, could be weeks could be days  and I'm always different. My husband and I have unprotected sex all the time and have yet to become pregnant. I told my obgyn and had my thyroid checked, and that was fine. My hormones are a little iffy but looking better. I am now on the pill to try and regulate things. I'm 23 and have never been on bc in my life. But I am frustrated now because now I deff can't get pregnant since I'm on the pill. I'd this doesn't work. Idk what I'm going to do. We've been trying for 9 months.
