8 days DPO... AF coming or maybe BFP?

So, I'm 8 days DPO. On day six, I started getting weird cramps (I usually only cramp on day 2-3 of AF), felt almost like a slight pulling and comes and goes. I'm also very tired, falling asleep pretty early.

These symptoms have continued along with my nipples being really sore, a slight backache in my lower back, and I also tried to eat pizza (my favorite good yesterday) and just wasn't about it, which is bizarre. I'm TTC, so I'm wondering if this sounds promising in any way for a BFP or if I should not get my hopes up. I hate waiting to test!
