4 tests and hcg bloodwork

I’ve taken a total of 5 tests. The first two were faint lines so I took a digital in the middle of the day and it came back negative so I took a regular cheap one and it had a faint line and then this morning I took the second digital and got a big ole positive. I started bleeding shortly after so the doctor sent me for blood work.

This is baby #4 and I’ve never experienced bleeding and I’m freaking out. Any prayers and good vibes are greatly appreciated.
