I have been on the Depo-Provera for two months now, and I haven’t had a period since, me and my boyfriend had sex and he ejaculated in me two weeks ago, since last week I’ve had period like symptoms, and I looked up pregnancy symptoms and some of them fit what I’m experiencing, like period like cramps, backache (only a few days of it), headaches and moodiness, is there a chance I could be pregnant?
