What does light brown thin virginal discharge 4 day before my period might indicate? I looked it up and it said possible pregnancy. I was just recently put on birth control and had sex on the 7th day when the doctors said it started working. He pulled out so there was no direct sperm in me. My chances were also 15% of pregnancy that day. The next time I had sex I was on day 15 of birth control and it was multiple rounds but still he pulled out each time. Should I be worried??
