I'm really scared because over two weeks ago I had sex but I used a condom, I'm cramping and have my usual symptoms of PMS. Though I am not spotting or bleeding. Last month my period last 10 days which is very abnormal for me. I started my first birth control pills two months ago and I will be starting the Third month on Sunday. I take Lo Loestrin Fe. I've been peeing a lot but I don't know if that has anything to do with it. I've had odd cycles before but I'm just very worried. Should I take a test or should I wait? Please help.
