Shorter cycle after pregnancy

Amy

So before my first pregnancy, my cycles were 28 days w ovulation at 14 days. Since having my daughter, my period came back at 8 months. It’s now 25 days and I ovulate day 16 now. So I no longer have the “2 week wait.” We’ve been TTC for 6 months now. Is my shorter cycle/LP the reason I’m not getting pregnant? Is there anything I could be doing?

I know 6 months isn’t long, but we conceived on the first try the first time.
