Darker tests

I have become the person who takes a test every couple days to make sure it’s still there/darker. This is my first baby and until I can go to the doctor I am just paranoid. The lines keep getting darker and I’m just hoping for a healthy pregnancy. The symptoms are in full swing. Nausea often, boobs hurt.. before this I barely felt anything touching my boobs or nipples. Based on last period I am 5 weeks tomorrow. Excited to get to go to the doctor. Twins run in my family so interested to see if it’s one or two babies.
