Help. Ovulation?

Rachel

My periods have been odd since I stopped breast feeding a year ago. My baby is 2 next month. We are now trying for number 2. My cycles range from 30 to 40 days. Today is cycle day 30. We have bonked pretty much every other day from cycle day 10 until now but iv not felt that iv ovulated. Prey test negative today but just got this ovulation text result. Is it possible to ovulate on day 30?
