I had a baby 7 weeks ago on Friday, and decided to test just because my fiance and I have had sex since I've given birth twice before 6weeks pp and once after 6 weeks pp, but the most recent one he pulled out. I took a test last Friday and the line was so faint I marked it up as either leftover hormones or maybe I was just seeing it because you could see it in person but not in the camera no matter how I took the photo. I took another test today and the line is still vvvvf but it's for sure darker than the first test I took here's photos of it:

It's been BARELY over 2 weeks since the first time we've had sex and under 2 weeks since the second time.

I guess I just feel like I can't be pregnant again?

ETA:

It wouldn't be left over hormones because this test is a lot darker than the first test I took, that means hcg hormone would be increasing, right?
