opk difference

These opks were taken with the same urine sample.
Its like a major difference. I know the pink isnt positive but it looks close. The other is way way negative.
Anyone use clinical guard?

They both have the same sensitivity level?

to be honest I dont know the sensitivity of either but it seems like a stark contrast!
I'll try and look up the sensitivity

Yes it must be somewhere on the package. My normal one was 25mui/ml and the extra sensitive one was 20mui/ml but you also have a 10mui/ml one...

so strange that they both say 25 miu

Yes then it is def strange. Both new i assume? Atomic says always bd on first pos opk from whatever brand.. but maybe there is something wrong with either of the brands.. really annoying! I used the cb once and gave me 9 days of smileys.. opks can be crazy.

I read some reviews on clinicalguard and it seems it can have lighter lines than other opks. So dont know which one is the cg in your pic?

the clinical guard is the lightest one. I only have a few of the other ones left..Ill test again later.

Yea opks can make me a little nuts!!

OPK are such lousy technology, the unfortunate thing is that they're all we've got.

I like you guys to go with the first positive of any brand because you can get pregnant from an attempt too early, but not one too late! So I figure better to attempt than to wait.

But I also like to see people pick it up with e4d after the pos OPK attempt to cover in case the first attempt is too early.

great advice!!!!
Thanks
