Should i be worried??? Please help

About a little over a week ago I lost my virginity to my boyfriend and there was some spotting for a few days afterwards, but now I’m 13 days late for my period. I sometimes have irregular periods, but i never thought too much into it. Yesterday while i was having sex with my boyfriend, a lot of blood came out so i assumed i started my period, but it’s the next day and there is no bleeding and only very faint spotting. Should I be worried?
