I've tested many times before for pregnancy and have had all negative except for one that was chemical . I'm testing on Thursday and this time feels different . I'm actually genuinely excited . I'm pretty sure it's going to be positive. I've never just had this feeling before that I'm going to see 2 lines . What's the best one to get to detect early pregnancy ? First response or clear blue ?i caught my chemical pregnancy with the clearblue digital test . But that ones expensive and would rather use a dye test this time .
