Poor progression


I feel like my progression is not going well... 4w4d and after only taking cheap tests, I took a clear blue today and barely any line showed up. Was there, but so so so faint. I’ve never gotten a strong positive, unless they sat for about 15 minutes. I’m worried about there being little to no progression. No bleeding. Slight cramping. OB doesn’t want to see me until July 24th. In order, Started testing on June 23rd. Three on the 24th, one on 25th and the clear blue today on the 27th. None were taken at the same time, but I still feel like some progression should be occurring. I feel like it’s going down.
