Confused

Last month on 12/2/2020 I had my stillborn daughter. This is my second stillborn and I’ve also had 2 miscarriages. With that being said i decided to get on birth control right away just so my heart could heal and I could figure out the next step. I didn’t stop bleeding till 1/2 a whole month after delivery. Well last Saturday I decided to take a test and it was super faint(refer to picture A) . I thought well it could be just leftover hcg. Two days later I took another test (refer to picture B) and it seemed to be darker. I told my husband and everything we were pregnant, going through all the emotions after being pregnant so early and trying everything to not let it happen. Three days ago I started lightly bleeding. Just a pinky watery almost more like discharge nothing crazy. I decided to test again because I’m paranoid with my track record (refer to picture C clearly negative) I thought well it could have been a chemical or even just left over HCG but now I know. Two more days now and I woke up (still haven’t had a peroid) and threw up!!! I decided to test AGAIN and it’s clearly positive again!! I’m so confused. I don’t know what’s going on with my body. Any insight on what’s going on ? Should I just call my doctor? I’ve been so hesitant to call him because I have really bad PTSD with all my loses and just can’t seem to pick the phone up. I’m scared because if I am pregnant it’s been a whole week and the lines are still faint and the light bleeding. I just want to know what y’all think.

(A) first test I took

(B) second test. Clearly getting darker

(C) third test. Negative

(D) forth positive again.
