Cheapo tests

I found out I was pregnant on the 22nd of this month. I had taken the blue dye test from clear blue and had a positive result. Line was faint but I could see it and then the next morning I took a digital test and it said pregnant! Yay! Over the weekend I took 2 first response line test (one in the evening and then the next morning) and they were both positive, line was way darker than the clear blue tests.

Today I took a cheap 88 cent test and the line was there for positive but it wasn’t very dark.

Should I be worried and go to the doctor about my levels or not worry about it since it was a cheap test?

Thanks in advance!
