What the hell is going on ?!?

Cm has been acting strange I'm 9/10dpo and have so far had negative tests but I'm usually dry running up to af and I've been between thin milky water cm so much I feel like I have wet myself and now this ? Has anyone had this before a bfp or just before af has showed up ? Any help is appreciated I've had subtle cramps aswell if that helps and cervix is soft and almost too high to touch thanks
