We had an intercourse with a condom on 8/1. My last period (first day of full flow) was on 7/20 and according to my usual 30 day cycle  I should have ovulated 8/4 or 8/5. So, on 8/4-8/5 I had some discharge and my breasts were sore moderately. Right now my breasts are still sore a little bit with no to very little discharge. Could I be pregnant? My next expected period is 8/19 or 8/20.
