late ovulation after early period

Hey all, has anyone experienced late ovulation after their period and early? My period came 4 days early this month so counting that as CD1, I should be ovulating now but no positive OPK 😢 This is our 3rd cycle since we miscarried our first pregnancy in early April and I'm scared we won't get a chance to even try this month. Should I count my CDs from the first day my period showed up (early) or from when it should have started if if were on time? Thank you all for reading and please answer if you can! 🌈🙏🌈🙏
