Early pregnancy symptom?

Maggie • Always stay positive no matter what 💕💕Baby dust to all✨🎉

Hey guys I know this might sound strange but every cycle after ovulating my boobs get extremely sore. But this cycle just my nipples are sore and my boobs seem a little bigger. Also I've been having slight cramps on my left side and my back has been killing me and I've been sleeping ALOT. I'm around 8/9 dpo is it possibly early symptoms?
