I need advice. I had unprotected sex in the middle of my ovulation window. Three days later I started to have mild cramping and then started to spot the next day. I've been spotting now for six days, a mix of brown, red, pink and a little white discharge. Could that be pregnancy signs or a red flag for a trip to the doctor?

I haven't been on the pill for years. I did have a mild case of endo two years ago though. Please help!
