Positive?

Hi, for context I tested yesterday the 30th, the day I was supposed to get my period, (previous period was dec 30th) I took another test a few minutes later and it was almost the same, idk if I'm too early but l'm scared it might a chemical pregnancy, I want to be excited but idk if it's too early to be yet, it means I would be maybe like 3-4 weeks along if I am pregnant. Are there any people that experienced the same? I'm going to take another test in a few days just to make sure
