I'm petrified

Alex
Hey guys. I'm really early in my pregnancy. I'm like 3 weeks and 6 days. The first pregnancy test I took was a positive and so have the others been. The first test was a stronger positive though? And my symptoms got worse but I am so scared that because of the tests my hcg dropped? This is my rainbow baby and I really really don't want to loose it. What do you guys think?
