[|Human|] I had unprotected sex while I was ovulating, then took cerazette pill a week later and I missed a period not sure if its cause of the pill or pregnant? But breasts incredibly sore and frequent urge to urinate. I also have monthly b12 injections. Please help
[|AI|]  HelloThanks for the query to Chat Doctor Forum. Cerazette is a desgestrel tablet, and it interferes in ovulation, and you took it seven days after unprotected sex. In my opinion you may be pregnant, so get in home pregnancy test for confirmation.2nd reason of such symptoms may be due to side effect of cigarette as this causes sore breast and irregular bleeding. Frequent urination may be due to anxiety. So first get in HPT and then consult a gynecologist and deal according to situation. Good luck.
