8 weeks and lighter lines..

I’m freaking out right now... last week on Friday I saw baby with a heartbeat of 153bpm. Today I decided to test (I know I shouldn’t have) but I did. The test was lighter than the control line I was getting dye stealers at some point and I wouldn’t be freaking out so much since I’ve heard at some point too much hcg causes the lines to go lighter so you need to dilute your pee... but I’ve been peeing so much so my pee wasn’t that concentrated but even before with diluted pee I was getting dye stealers. Now I can’t stop worrying...I don’t see my doctor for another 3 weeks..
