Ovulation, when should I test?

Question

When am I most fertile and when should I start taking ovulation test?
What can I do to become fertile? 
I’m concerned because my periods are so irregular.

Answer

How irregular ?

Answer

Generally you start testing the first day after your period ends once a day, then twice a day about 5 days before ovulation. If you’re not sure when you might ovulate id maybe do it twice a day until you have a better idea. There’s a lot of cheap lh strips on amazon. I use Easy at home.
