Late Period?

So Ive had my period for just over two years and I'm used to irregular periods but I always get stressed when I'm late. Basically my boyfriend of 1 and a half years and I were talking about having sex (both of our first times) and we decided that we were ready so he got some condoms but as we were about to do the dirty he put he's tip in and I freaked out cause it hurt like a bitch and said I wasn't ready. This was fine with him and we cuddled after. But now my period is late and I know it's paranoia but any advice to induce a period or decrease stress? Thanks x
