Pregnancy symptoms?

I had a miscarriage 2 1/2 months ago and I'm currently 8 DPO. I've been getting hot flashes all day and cramps on my left side and I started breaking out really bad yesterday and I'm extremely irritable. And gassy!!! Also my male cat who doesn't care for me has been stuck to my side all day and he even slept in our bed for the first time. Could these be early pregnancy symptoms or could it just be AF coming? I know it's early but I tested today and got a negative so I'll test again in a few days.
