11/12DPO! Is it just pms?

I’m extremely fatigued.. my lower back has been hurting the past few days. My breast are sore on & off but nothing severe besides this sharp pain growing through my nipples like twice. I’m having tons of food cravings.. like specific food cravings. & I keep having these vivid dreams about getting a positive on a test or being pregnant. I’ve been testing since 9DPO & all have been BPN! No implantation bleeding or anything. I understand only 30% of women actually gets implantation bleeding. Starting to think it’s just normal pms.
