I’ve learned this the hard way and I believed I had 2 chemicals last year, but now I’m doubting myself because I allowed the pregnancy test to literally brush against the lh test here and check out the line! I may have done this before when I thought I had a chemical!
I took this at 4 dpo so I knew it wasn’t going to be positive and also I got my period when it was due
just to warn you not to do an lh test at the same time as a pregnancy test and also not to keep them next to each other.
There was one cycle I kept getting faint positives and stark white negatives and now I’m thinking this was the reason
I would sometimes dip them at the same time or allow them to develop beside one another and the dye is so easy transferred
hope this saves a few hearts!
