Should i be worried??

Okay so 2 weeks ago my bf came over and tried to do it for my first time. All we did was foreplay really, when he tried to put it in, he had a really hard time because he said I'm too tight and i guess i wasn't really wet. Apparently his tip kind of rubbed against me but didn't go in at all, there was no cum or precum from him either. I'm worried because i was supposed to get my period around the 16th and its now the 22nd and i Aunt Flo hasn't visited. And then this app didn't give me any red days for this month and tells me my cycle is good and and i have red days til the 16th of June, what's going on!? 😭
