Aching and cramps..

So I posted a post here a few days ago about having cramps in my lower stomach like I’m having my period. I now started to feel it in my genitals like aching/cramping & now my boobs are getting super sore. I’ve got about 9 days until my next period & 4 days DPO. I feel kinda concerned. I never felt like this before especially how far away my period is still. Has anyone went through this before?
