Faint Lines for Days

Alaysha

So, so confused. I took a pregnancy test on Feb 7th and it was a faint, faint positive (HCG strip see picture) BUT I had taken the test and left it in my bathroom and went back three hours later to check and it was there, so I threw it away thinking it was a evap Line. Thursday, 2/15 I took two test and both are light, light positives (See HCG and 1st response pictures) Saturday (see first response picture) and Sunday (clear blue and no picture) I took two more and they are still super light.

I just suffered my first pregnancy that ended in miscarriage in December and I am thinking this one might end the same way. My pregnancy symptoms are super different between the two, which is also throwing me off. Anyone else experience this? What’s going on with my body? Why are my lines not getting darker?
