Help!

Okayyy, so I’m 8DPO. My boobs literally feel like their going to explode. Like, they actually might 🙃 I’m very nauseous with how much they hurt. With it being this early, would I have a symptom like this yet? Or could it be early pms? My boobs normally don’t hurt until about 3 days before AF, but it’s never this bad. 😭
