Hello, I'm a 17 year old who had sex on January 21 and the condom broke when he was pulling it out. I took plan b within 2 hours but we had sex again on the 27 of January and the condom didn't break or anything. But it's been 11 days since I took plan b and I've been having brownish discharge and I don't know if it's a sign of pregnancy, I'm really scared. Please help
