HCG levels might be low?! HELP

I’m 7 weeks and two days. And I feel very sick with absolutely no appetite, but my boobs aren’t very sore at all. Only a little twinge of pain if I actually poke one. I’ve been having some cramping that is very mild with no spotting. I’m really worried it’s a missed miscarriage. I ended up taking a test to see what it looked like. Last week I had so much HCG the test line was super dark and the control was actually pale. Today when I took one, the test line was just as dark but the control was only slightly paler.

Top picture is from last week, bottom picture is from today. Both pictures were taken after 5 minutes. I know the only way is to get my blood/get a scan but my scan isn’t until the 11th and the clinic us closed today. I’m aware these things aren’t very reliable, I’m just worried. Has anyone had any experience with this?
