I used the calista saliva ovulation test and to be honest i didn't think much of it. I found it was very confusing, but it could be different for other people.
I have a maybe baby ovulation scope. Personally I think they are a load of crap, and I don't use mine anymore, they are expensive and really didn't work for me. Even my DH got ferns, which is suppose to be a sign of ovulation, either he's keeping one heck of a secret from me or they are useless!! lol
Yeah, i've been using the saliva tests...it's okay. You can definetly tell when there is ferning. My first month, I was like "okay, is this ferning, or blobs...??" But when O day came, I really saw ferning...there's no mistaking it. I know that I do mine first thing in the morning, because you are not supposed to drink anything, brush your teeth or eat prior to doing it. So morning seems to be good for everything else in my kit, so might as well. I got my whole kit from Luna Fertility.
I also do the saliva tests with temperature, and OPK's, Plus, CM and CP.
I have a focus one from babystart....just started to use it, but it's simple takes 5 mins and easy to focus. i'll be updting my chart so hopefully it will coincide with O day this month...also using BBT, CBFM, CM and OPK too
