Pregnancy test line progression. HCG HELP!!

Hello girls here needing your opinions again for my pregnancy tests. On Thursday, I took the first "first response" test and I saw a very clear line. On Friday I did it but the economics and it was already much stronger and I was surprised. But on Saturday it was barely visible. I got very sad and went to a lab and it came out positive. Well, today I went back to the cheap tests and it still looks very clear. I do not know if it's normal. Has it happened to you? I will re-Test in two days!!
