Please help!!

So me and my boyfriend had unprotected sex, and my period is 8 days late, however they’re usually irregular and often late or sometimes really early.

However I’ve been feeling really sick and nauseous? I’m also feeling hungry CONSTANTLY yet I can’t bare the thought of eating 🤢 and I’ve also been non stop on the loo but barely peeing (sorry too much info). I’ve been drinking loads of Evian water as well.

I am on holiday and I understand different things can cause this but just wondering if anyone’s experienced the same or if it is pregnancy? Xx
