Just need to vent🙄

I have my body on track and ovulating on it’s own after dealing with irregular periods due to PCOS, it’s been about a year or so of no missed periods or issues with ovulation. BUT IM STILL NOT PREGNANT. I feel like wtf am I doing wrong? Everything is timed and done exactly right😩 we’ve been trying for a little over 2 1/2 years and I’m just getting irritated and angry! I’m on prenatals and he’s on fertilaid for men, is there anything we should be adding? We’re 21 and 24 WTF😞
