Ovulation

Jenna
I'm new to all of this. Been off both control for almost 2 months. I started taking ovulation tests and to my surprise it matched really close to when glow said I would be. But I'm wondering a few things. 
1. Can I have an LH surge for more than one day? I had two tests that both looked positive. 
2. Is it best to have sex right before ovulation, or during ovulation. 
3. Any thoughts on position and whether or not female orgasm matters? What about peeling after sex? 
If it helps, I'm 29, my husband just turned 30 and we have been married for a year and a half... In case it helps you understand something about me. Thanks!
