Annoyed

Having random, irregular periods is getting old fast. I never know when I'm ovulating, or when to expect my period. Sure glow helps me to guess better but that's all it really is, a guess. I want a baby so bad but TTC is nearly impossible with such a f*ck ed up reproductive system. Anyone have any advice? Besides just going to the Dr. I know I can go to the Dr.... I'm looking for any tips beyond that.
