I was on depo provera 9 months my last shot was number 2014 still no period, me and my husband have been having unprotected sex a lot and now it started a couple days ago I have been getting very nauseated in the mornings, and my breasts has becoming tender. Could I be pregnant?

That or something else. Tender breasts most often means your period is due soon... meaning there is a chance your period might be returning... or at least is close to it.

ANY time there is penile insertion there is the risk of pregnancy. You can minimize the risk but not eliminate it. So yes, you could be pregnant. But I doubt if what you are feeling is due to pregnancy. The first physical manifestation of pregnancy is a missed period.

? Now it started ? What just started, period ?

But while it is possible.

Yes, if you are saying that the nausea and breast tenderness are what started a few days ago, it could be due to pregnancy. Since it sounds as though you haven't started periods again since your last injection, you may not have a lack of periods to go by as a possible sign of pregnancy.

If your symptoms continue, you could try a home pregnancy test or see your doctor for a test there to see if pregnancy is the cause.
