Ok so I was taking birth control pills and then I got sick and had to take a rocefin shot and antibiotics in which my bc didn't work anymore. Me and my husband have been having unprotected sex and now Im having cramping pains in my abdomen, headaches, and some lower back pain. I took a test last week and it was negative but I think it was too early still. Does I get sound like Im pregnant? Or just paranoid.
