I've been bleeding (on my period) since I got it inserted. Last week my boyfriend and I had sex 6 times. He ejaculated inside of me every time. And my bleeding just up and stopped yesterday. My cramping has stopped and I've felt sick (flu like; nauseated, weak, fatigue)... At first I thought maybe it was just hormones and all that stuff from the birth control. But my period has stopped and it's been heavy since I got on this birth control and went from bleeding like crazy to nothing in the blink of an eye. Could I possibly be pregnant?
