AF due monday the 20th. My SO and I had sex Wednesday the 14th before we got out of bed in the morning. I went to the bathroom after and there was blood on the towel i used while i made my way to the bathroom, and some in the toilet. I spotted for a couple hours and then it completely stopped. Its been 2 days since and no more bleeding at all. Could that have been implantaion bleeding? AF due in 2 or 3 days and i dont wanna test cuz i feel like it still too early.
