I had unprotected sex with my boyfriend a few days back. A few things I want to set straight is that I am on Nexplanon, and him and I had sex before without a pregnancy (several months ago.). Several days ago, my boyfriend and I had unprotected sex, and afterwards, I had light bleeding from the sex. The following day, I did not bleed at all. The day after that, I had a spotting but after a few hours, I had this pinkish-red discharge. Today, when I checked myself, I was having brown and red discharge. I'm not quite sure what to make of it, and I was hoping you guys could give me some advice.
