Need Help

High

I had a misscarage and had a d and c Nov 2. I had my period Dec 16-24. I did not have a period at all for Jan. I havent started. I have taken a lot of test and all are negitive. Maybe im too early for the test to pick up? Im working on my 7 week without my period. My friend said maybe my body is still getting back to normal. please guys any thoughts would help. I dont know how to feel right now.
