So I recently miscarried on December 11th,2018 and had my first period January 7th. Earlier this week.. Tuesday to be exact I took a test for the hell of it and I got 2

faint lines, so the next morning (Wednesday) I took another test and got a faint line so I called my doctor and she called me in for bloodwork the same day. The Next morning I took another test and it came back negative and my doctor said that my bloodwork came back negative as well. My period was expected to come Friday, but it still hasn’t arrived. I’m so confused as to what could be happening. Has anyone ever had this type of experience?
