Chemical then not a chemical…?

Maeve

Got my first positive at 10 dpo on July 16. My lines never got super dark. Then they started getting lighter and I bled heavily for 3-4 days. I just assumed I had a chemical and moved on. I didn’t go to the doctor because I figured my body would just do its thing since I was barely 4 weeks.

Since then I have had horrible headaches. I started bleeding over the weekend again. I took a test yesterday (2 weeks after initial bleeding) because I thought maybe I still had some HCG left in my system and that’s why I was feeling sick. It was positive. Had blood drawn at the doctor also yesterday and HCG is 55. Today I took a test again to see if the line is getting lighter. Well it got darker. I go for another HCG blood draw tomorrow. But I’m just so confused and wondering if anyone else went through this. The top pic is my lines getting lighter the week on July 22. The bottom pic is yesterday and today. There’s no way I ovulated and got pregnant again in 2 weeks. Help 😫
