Bleeding during ovulation

Lindzi
My partner and I have been TTC for about a year now but since my teens I have had irregular periods. This has made it hard to predict ovulation etc but I have used the app to track everything to try and get more of an idea of my body's cycles. I have an appointment at the doctors next week to discuss TTC as we have had no luck so far l. However, from the app I should currently be ovulating but have been bleeding slightly over the last two days and it is unlike being on a period. Is this normal? Has anyone else experienced bleeding during supposed ovulation? Thank you for any help
