Hello doctor,
My period started 12th of last month. I reviewed the Depo shot two days later. I had unprotected sex nine days later. He ejaculated in me several times. I thought I would be protected but I am also having symptoms of ovulation like high (hard) cervix with a sharp pain in my ovary, then I had spotting for three days (brown to red then to brown again). What are the odds that the Depo is not effective for me? Is it common to experience ovulation and period symptoms on Depo without actually releasing an egg?
