I've been taking medroxyprogesterone 10 mg for 10 days of the month. I've been on it for about 4 months for irregular periods. it's been working great, I've been getting my period 2-3 days after the last pill and they last 6-7 days. I took it this month and my period is not on 3 days late. my doctors think that i have PCOS but i haven't been diagnosed. when i had an ultrasound everything was fine and i have no cyst. I'm just wondering if i could be pregnant, or am i back to square one with the irregular periods.

Dear Curious,
You are very insightful. Before we had pregnancy tests that detected the hormone hCG, doctors would give women progesterone and if they didn't have a menstrual period it was a sign that they might be pregnant. So checking a pregnancy test is a good starting place.
If you are not pregnant, don't worry that happens some time. If you are trying to get pregnant and have to take the progestin every month then you probably still have a hormone imbalance that is preventing ovulation. Your doctor can do some tests to make sure that you have a correct diagnosis and then most likely he/she will prescribe something like letrozole, tamoxifen, clomid or another medication to help you start cycling (ovulating) on your own. Good luck!
