Two months in a row now, I've gotten a positive OPK around day 12 or 13 in the afternoon that is negative by the next morning, and then a second positive a few days later, around day 14 or 15.
Last month, I ended up going for an ultrasound the day after my first positive, and my follicle was only 14 mm. I had a second surge and then went for an IUI about three days later.
Has this happened to anybody else? I don't have any idea what is going on with my body, but why would I surge twice like that two months in a row? I thought last month was just a fluke.
I use the Clearblue Digital OPKs with the smiley face, so it's not as if I'm reading the results wrong.

Re: Two LH surges days apart?
I had this happen to me, but I have PCOS so it's not abnormal for that to happen to me. I think this can happen from time to time with anyone, though. Has your RE weighed in on what it could mean, since it's happened to you a couple of times now?
Me = lean PCOS;DH = poor morphology (3%)
3 IUI/TI cycles = BFN
IVF #1 with ICSI: antagonist protocol = BFFN
IVF #2 with ICSI : Lupron downregulation = BFFN...FML
IVF #3 with ICSI and AH (Antagonist) = IT'S A BOY!!!!
