So I'm in a treatment with ampicilin and I'm taking birthcontrol pills. I've been taking the antibiotics for 8 days and I've using condoms during all that time because I know the birthcontrol may lose the effect because of this, but today we didn't use condom and I went to clean myself after having sex and I had a lot of blood, I'm in the middle of my cycle and I know it's posible to have some blood spotting during these days but this was way more than just a spotting, it looked like when you clean yourself during your period. Is this normal?
