Hello everybody, I have a serious question that needs an answer ASAP. So my girlfriend and I are sexually active, we've had sex with and without condoms, but she always has really irregular periods. Last month it was the end of the month, and that was about 35 days after her last period. But not it's the 27 and she said she's been having brown discharge coming out of her for like the past 3 days. What is the cause of this? Please don't tell me she's pregnant. What can cause this and what can I do a a boyfriend to help?
