Ectopic Pregnancy and now TTC

Alysha

I had an ectopic pregnancy and a Fallopian tube removed two years ago. I went back on the nuvaring afterwards. My husband and I are now TTC so I took out the nuvaring mid cycle, had a period, and I'm supposed to be on day three of ovulating but I took a test and it was negative (again!). Could I only ovulate every other month now due to the missing tube? Or do you think the nuvaring messed my cycle? Any opinions would be helpful!
