Should I hope for BFP?

Im 8dpo I’ve been having kind of pulling sensation in my lower stomack and from 4-7dpo my lower back was hurting (i dont usually have nothing like that, it specially that bad that I can’t really sit properly to be comfy), this morning my mc was clear and sticky but as the day went by it got watery and clumpy and a lot of discharge today (as well, dont get that usually) . My nipples are sensitive, I’ve been eating a lot today as well. I think its all in my head, but I wanted to ask.
