first time using this app and trying

Natasha • I am TTC baby #1 with my SO. I am 28 years old and he is 29. We live in Northern Cali and have been together for over 3 years.👼🏼
So I downloaded this app yesterday and logged what I could, I just turned 27 and my bf and best friend of 5 years decided we aren't getting any younger so my ovulation dates are march 3-7th and the highest is 32% is that normal/okay? I've been off bcp for 3 months now but have been nine stop on it since I was 15. I'm hopeful we can get lucky our first try. After sex I lay with my legs crossed keeping the semen in me.. any suggestions on after sex and keeping the sperm inside before I get up and having it run down my leg...?
