Nipples!! LOL

Hi everyone! I am around 6/7 dpo, and I am having the most sore nipples ever. Usually is not a AF sign, my boobs are tender but it has nothing on my nipples and how sore they are. Right now my cervix is sorta high, lotioney CM, and I’ve been having mild out of the blue cramps off and on since yesterday. Not many but like a bolt of lightening in my uterus/cervical area a few times a day. Anyone think this could be my BFP? Or just Aunt Flo?
