So my husband and I had unprotected sex on the 26th which isn't suppose to be a fertile day. But we were going to try and start getting pregnant in a few months..Ive been having brown discharge or spotting. I looked it up and could be different things but it's a week before my normal period so I'm not sure. Wouldn't be my period already. Need info or help. If it's pregnancy it's probably too early to detect from test I'm sure.
