How high can a peak T/C ratio go?

Ha

Hi, my husband and I have been trying to conceive since December. My cycle is usually 32 or 33 days. Getting desperate at this point so I bought some OPK strips and got a thermometer to start measuring. This is my first month measuring everything. I’ve never seen a peak this dark before. Has anyone else gotten one this dark? The picture was taken 5 minutes after the test. Also I’m still getting used to taking my temperature, I missed a few days. I guess this means I’m ovulating on cycle day 19, which is later than expected. I had sex twice yesterday which was a record.. we really want a child. I’m used to having sex 1 every 2 weeks so this is a big jump as you can see in our chart. My question is, do you think I’ll miss the surge if I wait until tonight? Or should I try to do it as soon as possible? We had sex 2x yesterday so I want to make sure his sperm has enough time to regenerate. Looking for any kind of advice or tips.
