HELP positive and negative opk!

Ok so i have been testing since c8 and had positives since cd 12 but on the pic they dont look positive anymore except this mornings, so i had to take another one at 2 to see if it was still positive, i decided to take a one step (blue handle) aswell as the normal one i use which is the green handle, how on earth can one be positive and one negative i am very confused, i woke up with sore nipples yesterday and they are worse today and i had sharp pains from my right ovary area yesterday, my cervix has seemed open for a good couple of days now, i havent noticed ewcm because i cant tell the difference between that and seamen, can anyone explain the negative opk :/ i wish i had just stuck to one brand now xx

I don't know what to say here... if you have a digital OPK try to use that and do best out of three.

I dont but i just went with the positive one as its the one i have been using all cycle i have ovulation symptoms and all my apps predicted ovulation as today so i am pretty confident i ovulated today.
