I’m getting worried

i know line progression isn’t a good indicator. But it really worries me that my lines are equal this morning when i got my first positive on 10/30. i mean with my HCG levels being checked last week they were more than doubling each time i feel like my control line should b lighter then my test line. I’m so beyond worried something is wrong. We are supposed to have an ultrasound tomorrow and I’m about to have an emotional breakdown.
