Confused this month!

charlotte

I’m currently 13dpo and have been having PMS like cramping from 9dpo, I’ve tested up until 11dpo and gave up because I am convinced it’s AF as they were neg:( I know I am not out till AF shows up but I am disheartened. I usually get sore boobs when I start cramping but this month I haven’t which is strange, my cervix is also really high kind of sort but firm and not opened at all, mucus is watery / milky so I am confused 😕
