DPO questions, help pleaseeee

So I was about 7 DPO and started getting these mild lower abdomen cramping, my period is literately 8 days away and it’s five days later and I still have some mild cramping, it comes and goes. Is it just PMS symptoms? Has anybody still gotten a BFP with these similar symptoms ? Or is it just AF? I normally never cramp 8 days before. Idk if I’m just stressing myself out because I’ve been TTC for a while now. This stress is just making me not want to conceive anymore.
