The waiting game

This is our first month not preventing pregnancy, and TTC since having my son 2 years ago.

We BD the day before positive ovulation test, day of, and day after. I’m now 10dpo, period due this weekend.

Numerous negative tests so far. My question is this... I’m a little unclear on when to start taking ovulation strip tests. I know you should do them days in a row, 2x a day about 10 hours apart. Could someone help with this question?

Also, once I have a ‘peak’ am I ovulating at that time or does ov come after that? It’s all so confusing! How often to bd?? Help!
