Hey, I'm very new to this. Just wanted some advice. I started AF at the beginning of this month and it lasted for six days. Since then me and my long term boyfriend have had unprotected sex 4 times. A day after the last time I noticed some brown discharge. I'm not due AF until the start of next month and my periods or on time or only ever late, never almost two weeks early. This discharge has lasted for about 4 days and it isn't heavy I just need to wear a pad. I'm a bit scared incase its something serious or if its something to do with not being able to have kids. If I was pregnant it would be wonderful news. Any advice would be much appreciate
