Pregnancy symptoms or Period ?

So I had unprotected sex 2 days before my ovulation, I knew I was ovulating because I get bloated, and cramps with sensitivity near ovaries. I noticed mild cramps around 4-5 dpo, and my breasts have been sore and tender for almost a whole week. I’ve been way more tired than usual and hungry😥 also I had some nausea after eating popcorn😬

My period is due to come now in 3 days. Idk could I be pregnant or I’m just overthinking 😓
