Chemical but still a vfl?

Megan • Twin baby girls 12/2021. 💕 Baby #3 due May 2024 🤍

I need some advice to ease my mind before I go to the doctor tomorrow morning. About 3 weeks ago I got my first bfp two days before af was due. The lines got stronger for a few days and then started to fade. On December 10th I started bleeding and the tests were so faint I considered them negative. My period wasn’t heavy but was fairly normal. I was out of town while this was all happening and the day I got home my dog died and my two little girls got very sick. In true busy mom fashion I didn’t go to the doctor and assumed I had a chemical pregnancy. Now today, 17 days later, I took a cheapie test and still got a vvvfl. How long would it take for the HCG to leave my body? I’ll post some pictures for reference. Any words of advice are appreciated.
