Paranoid, HELP!

So I’m 4 weeks and 5 days, just found out we were pregnant on Wednesday. I had a blow draw to confirm, my HCG on Wednesday was 27 and my progesterone at 6.9. So doctor ordered another low draw on Friday and put me on progesterone supplements. Since my doctor office closes early on Fridays 🤦🏾‍♀️ I have to wait until tomorrow for the results. So this morning I decided to take another pregnancy test and the lines are not getting darker! 😑 Should I be freaking out? I had a miscarriage once in May 2015 and then had our rainbow baby shortly after. So the miscarriage fear is real since I’ve been there before. I still “feel” pregnant. Ugh.
