So I had a period on the 3rd of August till the 8th. Had sex on the 18th Aug round about ovulation time with no condom. Due on the 1st September but period didn't show up. Took loads of tests all come back really really paint positives. Went for a scan on the 23rd September but they say they couldn't see nothing but I'm sure I can..will upload a picture with the scan they took. Had negative blood test that day to and negative test. So confused. Just missed this month's period too by about 3 4 days now. Still negative tests. I don't get it.
