Don’t skip❗️❗️ANY ANSWERS? 🤧

I’m 21 years old! I was suppose to start my period on the 5th of this month! I have been late 3 days before, but never this long! I took a test 2 days after AF was suppose to show and it was a BFN. I have been getting AF cramps since I’ve been late but no period! I took a test yesterday also. But didn’t get to look at it until it was past the 10 minute mark, but it’s a vvvfl on it. Also I have been having a lot of CM! I mean ALOT! It’s makes me think I have started my period. It’s very watery. My nipples are very sore and have been for the past week or so! Any answers?
