Ovulation with HCG?

[downwardsun]

I had a natural MC 3 weeks ago. I've been using OPK's since then. This past week I had two days of positives around the same time I usualy O in my cycle. But I am still testing very positive on HPT's. I'm also temping and have had three days of increased temps since the first positive OPK. I've also had EW cervical mucus right when I should in my cycle. Fertility friend has given me cross hairs. Has anybody else experienced this? I am going in tomorrow for an ultrasound because the doc isn't happy with my level of HCG decline...

HCG registers on OPK so that's probably making your OPK positive x

And that's what I thought except they were negative for 18 days after the MC and then suddenly positive for 2....
