I usually have 25 day cycles on average, give or take a couple of days. I started progesterone after I got a positive OPK, and my doctor said to stop it when my period starts. I’m now on CD 31 with no period. 3 days ago I took a HPT and it was negative. I haven’t taken one since, because I’m convinced it’s the progesterone. I don’t want to get my hopes up. We’ve been trying for 2 years and had 2 failed <a href="https://glowing.com/glow-fertility-program">IUI</a>’s. I’ve never had a positive HPT.
