Hey,
I also used a dollarama cheapy for my first test. This was my outcome...

It was so faint I could barely believe it and I even got negatives (CB digi,FRER and accu-clear) after that followed by more positives (Cb digi and FRER) and I'm definitely pregnant!! Wait a few days and try another test. Sometimes the expensive ones arent always the greatest either because they need more HCG to pick them up. Dont give up, your pics look pretty promising!! I had another friend that got her first positive pee test on a dollarama brand!! Good luck and let us know how you get on! xo
