I feel like my body is playing tricks on me😭😭

I’m only 5DPO. I feel super confident this cycle. But holy crap have my boobs HURT today and yesterday. It’s getting more painful throughout the day. I’ve never had them hurt like this. Its on the sides and my nipples. It’s so weird. My body has felt so off since ovulation. I haven’t had a period since March 20th-which is normal for me. I got my peak smiley over the weekend though. My SO is so sure I’m pregnant. I’m hoping and praying but i know it’s way too soon!!
