Is this ovulation?

A

Hi there! For reference, I have had four children in four years. My eldest is 3.5 (almost 4) and my youngest is 7.5m (almost 8m). I am nursing and have ovulated approx. 3x since his birth because I have followed my cm. This time around, my husband and I had sex, but didn’t use protection. I went to see if I was ovulating because I didn’t get a period yet this month and o was supposed to be on my period and noticed some runny cm. Thoughts?
