Faint line after loss

Mandi • 💕👼🏼🌈👶🏻 👶🏼 ttc 🤰🏼

Can anyone offer advice or help? I had a stillbirth delivery last month at 20 weeks. I had post delivery bleeding till about 10/15 at 10/18 I had a btt spike and a positive ovulation test. Had sex that day and on the 20th and on the 24th I felt a little pukey/spiny when I got up and thought maybe I should take a test - that was 6DPO & i got an extremely faint line every morning, and it’s not getting any darker. I’m currently at 9DPO and I feel like if this was another pregnancy it would be getting darker. And if it was a faulty positive - could I have really gotten 4? Or is there a chance that this is left over hormones from my recent pregnancy? I’m so confused! Here are pics
