Low hcg at 4 weeks but tests getting darker!

Hi there!

I miscarried 2 months ago so now I’m a very paranoid gal. I got pregnant again this past month and went in for hcg blood work at exactly 4 weeks and it was low (44). I went back in 48 hours later-so now I’m waiting for my results. I’ve been taking pregnancy tests everyday twice a day since then and they continue to get darker and darker. This afternoon after a 6.5 hour hold I took another test and my test line is now darker than the control line! This is a good sign right? Anyone have a low hcg like mine and continue on to have a healthy pregnancy and baby!? 🤞🏼 What was your second hcg level reading?
