I had a miscarriage in March of this year and again in August. After this last miscarriage I started taking progesterone shots once a week for 6 weeks. I finished about 3 weeks ago and ever since December 1st I've been getting almost positive opks, I haven't had my period since Oct 31st and pregnancy tests are negative. I took a test yesterday morning negative after 2 minutes and strong positive after 30 mins I know it must be an evap. But I was wondering has this happened to anyone? Clearly it's not normal and I've read it can happen with pcos ?! I've never had pcos. I'm just so confused and honestly so done and feeling exhausted with no period and negative tests.
