When to test?

Megan • baby #1 due july 12th!
I know I need to wait longer, and my period might come on time, but I just have this gut feeling. Had sex with hubby on 3rd ovulation day and he came inside me. I have had a lot of discharge, but zero symptoms at all. I just have this feeling that I could be pregnant. Should I just wait for my period to be missed to test?
