Is there any possibility of pregnancy for a patient who took emergency contraception, had a negative pregnancy test, underwent a medroxyprogesterone-induced withdrawal bleed followed by a subsequent normal menstrual cycle, despite a prior ultrasound showing a prominent endometrium?
The possibility of pregnancy is extremely low, essentially zero. Having a negative pregnancy test, a medroxyprogesterone-induced withdrawal bleed, and a subsequent normal menstrual cycle all confirm that you are not pregnant. The prominent endometrium noted on your prior ultrasound simply indicated a thick uterine lining, which has now successfully shed during your bleeding episodes. Your body is resetting beautifully. If you still feel anxious, a quick chat with your healthcare provider can offer additional reassurance.
