Chemical paranoia

I can’t stop testing to make sure the positive line is still there. I know many people don’t believe the whole darkness of the line means anything, but I test a lot and it’s driving me crazy. Good news is the lines are getting darker every couple days. However, the reason I can’t stop testing is because couple months ago I had a chemical, and the way I knew was because I tested one morning and the line was almost completely gone just disappeared. Went to the dr had blood drawn they confirmed my HGC levels dropped and it didn’t stick :( for me personally the pg test did let me know I had a chemical. So now I’m obsessed with testing and it’s driving me crazy! I don’t know what to do I can’t go through my pregnancy like this :(

Side note* last pregnancy (chemical months ago) the line NEVER got this dark
