Ovulation trouble

Tel

Can anyone please help me!

Since having my 4th baby my body has changed dramatically . My hair is oily constantly, Periods are irregular changing from 5-8 days of bleeding and a 26-28 day between them.

And I've been testing ovulation but I haven't seemed to have got a positive yet and only realised recently this app can read test too .

Pics are from a different app .
