Positive OPKs but low BBT... !? Help...!

Julie

Oookay so long story short, I got off BC in August, and got pregnant on my 2nd cycle.

November 23rd, I had a D&C following a missed miscarriage. I'm aware my body needs time to recover but I'm having a hard trying to make sense of it all.

I got my period on January 3rd. I started tracking BBT and doing OPK strips twice a day. On the 18th, the lines were equally dark on the evening test. On the 19th, the test line went even darker. And on the 20th, the lines were again equally dark. This morning, no more surge. The thing is, my temps are staying low and it's driving me nuts.

So my questions are :

1. Which OPK determines the surge? The first one, the one with the darker line, or the last one?

2. How long after the surge should I expect my BBT to start rising?

I'm in a panic right now, thinking the MC ruined everything and I cant even ovulate anymore ...!! 😔😥😲
