I did some more pregnow tests this morning and once again I had faint positives but they were lighter than the ones i did yesterday afternoon (my urine was more concentrated yesterday arv though). I also did I First Response test with my FMU today and it was negative. So Im guessing my pregnow tests are just evaporation lines?? Im only 10 dpo so is it possible that I may still not have enough HCG in my system for First Response to detect yet? I've used Pregnow heaps of times before and have never gotten evap lines
