Ovulation Concerns

Hello! I’m working on conceiving, I’ve been tracking my menstrual and ovulation. It has been steady for the past couple of months. I was actually going to try to conceive my next ovulation window which is the end of October beginning of November, but I’m currently 2 days late on my menstrual. Is it still possible for me to ovulate or get an ovulation date with me not having my menstrual yet? It’s very important because I’m flying out of town for this. Could I still try to conceive?
