7/8 DPO Symptom Question!

So yesterday I had two dizzy spells, and major food aversion around dinner. Husband wanted to order pizza and I wanted nothing to do with it, the thought made me queasy. Tried eating a salad and couldn't even finish it, it tasted awful to me. I've been super gassy, plus headaches and cramping. I had a LOT of thick creamy CM yesterday, to the point where some was in my underwear. AF is due next Monday/Tuesday and I've basically been cramping since my positive opk. I have no real breast tenderness though. Has anyone had a BFP with no breast symptoms? My husband is convinced I'm pregnant, but it's hard not just being convinced of the worst case scenario!
