period due😦

Kaylee
My boyfriend and I had sex 3 weeks ago and we used a condom and did the water test to make sure there was no rips or tears. Could someone put us at ease we are fairly new to sex and worry every time we do the deed! today my period is due should i calm down and should I get it because we made sure there were no tears or rips and he didn't even ejaculare inside of me while he had the condom on?
