Was anyone on progesterone in early pregnancy? I have been on endometrin since 3 DPO. My weekly blood progesterone levels have been 25, 15, 13, 27, 19, 18, 17. When it dropped to 13, my doctor changed my dose to 3x per day. I have been on that since. It still won’t go up. I’m 13 weeks and he’s continuing progesterone because he said he’s never had a patient not respond to the medication. Has anyone else continued to have low progesterone even on endometrin?
