My period was due sometime between the 3rd and the 7th. I took multiple tests and they’ve shown faint lines especially on the red dye tests. I went to the hospital 2 nights ago for flu symptoms which ended up being negative thankfully. They did a blood pregnancy test and my HCG level was 10. My estimated due date is October12th.

I woke up this morning with cramps and bleeding

Waiting for the doctor to call but looking for some insight. What do you think is going on?
