IVF - what to avoid

Michelle • 34, DH 37. ttc #1 for 4+ years
Hi all! I'm hoping to start stims on Friday - had to extend BC a week because I had a cyst left over (I guess I ovulated this cycle) - they are hoping the BC will resolve it by Thursday. I don't want anything to interfere with egg quality so I've pretty much cut out everything already (caffeine, alcohol, etc). But is it really necessary? My doctor didn't tell me to cut out anything, I'm just nervous about what could happen if I don't. I've been taking a ton of supplements as well to promote egg quality, but I'm dying without my daily dose of coffee! Thinking of drinking decaf to soften the blow, but I've read decaf isn't good either. Any insight you all could offer would be appreciated! Thanks!
