I had unprotected sex three days before starting the depoprovera which was january 8th , & i have had no menstrual cycle since december can i be pregn?

Its Possible: If you have already conceived prior to starting Depo Provera (medroxyprogesterone), (medroxyprogesterone) you will remain pregnant. However, many women on Depo Provera (medroxyprogesterone) don't have periods, so your lack of a period doesn't make it certain you are pregnant. Do a pregnancy test to find out. You can get one at a pharmacy without a prescription. Best wishes!

Do pregnancy test: Do pregnancy test and verify your status. If you are pregnant visit with your ob, as you would already be past your third month. Best wishes.
