Ovulation

Penelope

So I have 2 children and I have only been pregnant twice . I believe I may be interfile I can’t seem to get knocked up again . I had my last period March 27 that lasted 5 days. I had sex Tuesday (April 10th) I assumed I was ovulating.

I took a ovulation test Wednesday ( April and 11) and my ovulation test was negative .what are my chances of being possibly pregnant ?
