Worried about my cycle

Ra
Hello mommas! I need some advice. I had my beautiful baby boy February 9th this year. My husband and I are going to start trying for baby number 2 in November! I'm not breastfeeding and my period came back seemingly right on schedule at the end of March. I want to be ready and familiar with my cycle again come November so I've added ovulation testing into my routine. I noticed this month I've yet to have a positive ovulation test. My periods before I had my son were 24 days apart like clockwork and it was easy as pie getting pregnant with him! Looking back through my calendar I noticed my cycle has been anywhere from 24-30 days now! I'm just worried something might be off. Is this normal? I have an appointment with my OBGYN Friday, but I'm afraid she will be a little judgy with us trying to get pregnant again so soon. Any advice welcome! Thanks for reading if you've gotten this far!
