Hey all! Totally fine calling myself a dummy on this. I just want the basic 101 on TTC temp tracking, cm, opk’s...

So I have a few questions.

1) I bought a BBT thermometer. I read to take your temp every morning when you wake up roughly around the same time. Then I’m assuming I enter my info into this app and it tracks it nicely for me on a chart?

2) Temp goes up when you have AF and then again when you’re going to ovulate soon & are ovulating?

3) Is it best to have sex every other day in your fertile window (or say when I get a high LH surge on my opk up until ovulation day?

4) Or every other day until ovulation day and the day after too?

I’d love any advice you all have to give me! Thank you!!
