My period and ovulation

I have always had a weird period. I have pcos and I am kinda heavy due to it. And I am trying to get prego. I am on all the meds for pcos. But still nothing I have read comments saying 'get on metformin. You can get pregnant real quick.' something like that. I've been on metformin forever and recently started to try to have a baby tracking ovulation and want not. I don't understand it tho. Why is it that I need to check the white goop. ? Lol and than when I do it get my hoops up and think that an egg has attached to my wall cause I'm spotting a bit. But it's just a freaking period. Ugh I'm to broke to get infertility treatments or whatever it is. Adoption is way 2 expensive as well. This has turned into a rant.

Help!!!!!
