ok. HI!!! im new here and so confused! lol so I have 3 wonderful kiddos and my fiance and I are trying for our first together. I never activly tried with my ex husband it just happened. soo this is all confusing!! I bought the answer 20 pack of OPKs and they just dont seam to work very well. I had also picked up a few of the .88 ones from walmart and where i see what looks like a evap line on the answer i see a color line on the .88 ones. so my question to everyone is what OPK test have you used and have found the most efficiant?
