What could be happening

Cassie • 26- Married - 2 sons 🥰 - Baby #3 on its way!

Last period started January 12th and lasted 7 days. It's Feb 26th and I still havnt had a period. The app says im 10 days late. My pregnancy test is negative. I woke up thinking I started my period but when I wiped the wetness I felt was alot of clear watery looking discharge. I've never had that happen before and I've just had tons of it since this morning now like I'm just wet. Any idea?
