First time using OPKs

Hi! So after going off the pill in April, my husband and I conceived in our first month of trying (July). But found out it was a blighted ovum at our first ultrasound. I tried to MC naturally for a couple of weeks but it was incomplete and I ended up with a D&C.; Waited to get a period before trying again so October was officially our first month back on the wagon. We got a big fat negative, but my period was a couple of days late. I decided to start using OPKs this month to make sure my glow calendar is as accurate as possible. Got my first positive yesterday (2 days before glow predicated so the calendar updates of course today yesterday was the day) so we had sex. But today the result is even clearer.

What does this mean? Yesterday I started to surge but today is really more of the peak? Here are pictures of the 2 tests.

Yesterday:

Today:

Thanks ladies! When I entered another positive into today’s log, it didn’t update. Still shows today as 1DPO, but it seems that today’s result is stronger. And I know I’m OPKs you’re waiting for the line to be as strong or more bold than the control. I tested for something like 4 days and had a line fainter than the control and yesterday was the first day it was clearly AT least as bold of not moreso. But today is definitely way kore bold.
