Lots of cm 8dpo and weird temps... thoughts

Heather

So my bbt has been up and down but my temp overall through the day is crazy high for me(around 99) when I’m normal 97 or so. I’m also having large amounts of white/yellow sticky cm, sensitive nipples and some cramping. I tested early today at 8dpo and bfn of course but just wondering if my symptoms sound like a bfp could be coming??
