First cycle TTC - please help!

Kate

My partner and I have decided to start actively TTC and I have been tracking my BBT and LH levels. I understand we are best off BD every other day during my fertile window, but I’m concerned I’ll leave it too late if I’m guided by my peak on the LH test.

Are we best off starting during my predicted fertile window and then definitely BD on the day I get my peak levels?

Please help, as I am clueless and google seems to be confusing me more!
