TTC frustrated at my OPK

[tennessee635]

I've been having crazy menstrual cycles lately when I use to be a perfect every 28 day girl. Here lately i it's been 25 days if I'm lucky so I started using the clear blue 4 day kit. Well I started testing on cycle day 10 got blanks then on cycle day 12 I hit an automatic peak smiley which I thought was weird. So I took the test from the box last month and did a second test. It was blank. Tested the next day with last months test stick hit a blank. I figured my test from this month gave me a false positive. So I waited then on cycle day 14 I got a blinking I thought what the Heck I'll test again. I got unblinking smiley again the next day so I called clear blue and they said I ovulated on day 12 and the stick from last month is just measuring high estrogen And thinks I'm on a new cycle so I kept testing on cycle day 18 I got a peak smiley. Now this time I had cramping on both abdominal sides. So I'm thinking WTH. I didnt test on cycle day 17 so I'm hoping I peaked on the 18 and caught it in time. I'm now on cycle day 21. A little bloaty still but sex drive is high. God so frustrated and confused on which test is accurate and hoping I caught it in time. ANY SUGGESTIONS
