Good luck, I hope this is it for you!!
I totally understand the concern with those tests. I got 3 "bfps" on what looks like that same type of test (one test was a walgreens brand, and the others were walmart brand...but they were all created by the same company) a few cycles ago and wasn't pregnant. If you did a dollar store test, that might ease your mind a little! (If you take another test, you better post it!!)
