Free clinic

Na

So i found out today that im pregnant. I took two clearblue test. One was a line test which was faint but noticeable and the other a digital. I also took a cheap dollar test and i came up so faint i thought it was negative and my eyes were playing me. I Plan to go to my local free clinic to get tested but im worried that if they are using cheap test it wont come up dark enough for them to see. Does anyone happen to know if they do use the cheap test? Should a wait another week before i go? I do plan to see my regular doctor to get blood work but till i can get in this is the option.
