Ovulation

Hayley
Hi everyone, 
So I started to take ovulation tests on Tuesday for the first time. The one of Tuesday is the darkest and then they have only for lighter. I started taking them 10 days after the start of my period, as stated. What are your opinions on this? Is it possible to ovulate close to your period? Or closely after? Also my last period was only 3 days, when they usually last 5. #confused HELP
