My boyfriend and I had sex 6 days ago. (Day before my period should have started ) and rarely but sometimes I let him put it in raw for a few strokes (because it feels so niceeee) and then have him put the condom on so when he finishes in the condom. This app says I’m 5 days late and I took a test today and it’s negative. We have been doing medical marijuana from the dispensary alot recently and idk if that could affect my period or not?

My period has never been late this long before. But I took a test and it’s negative so when should I get worried ?
