I'm just curious

Hello ladies... I'm just curious, I see some women say things on here like "they have issues ovulating " & I'm just curious if ovulation if your fertility issue does that mean things like.. You don't get positive opks? Or you never have an lh surge? Or your bbt never rises? Could someone please explaine to me because I'm concerned maybe I have an ovulation issue since I have irregular periods.. I get positive opks but I do not bbt chart... Any advice or personal experience would be appreciated
