I have been on birth control for a month now.i had sex on the 30th of September. My period had just finished.He had pulled out to finish but then we went for round 2 a couple minutes later. and 7 days later I’m experiencing a very mild pelvic pain. I don’t feel it unless I touch and press on it but it still there. Could I be pregnant? I was also late ona couple pills that month. Nothing over 3 hours thou. The pill I take is lessina
