Help LH SURGE ETC

Theodora • TTC # 1 IVF 🙏 Unexplained infertility/endometriosis

I just want to simplify something for myself: the OPK strips test the LH surge in my urine before ovulation. If the test is positive is it in those days that I should have sex the most? Should I test every day after the last day of my period? Sorry it sounds stupid I’m just paranoid.
