I think it's happening again

Shaina • My husband and I are trying to conceive our third child.
5 months ago I Welcome my second handsome most perfect baby boy. Now 5 months later I'm on Day 49 of my cycle with no AF in site. April 25th was my last AF. I'm still testing BFN but a few minutes ago there it was (implantation bleeding). I called today and made an appointment for Wednesday to have an ultrasound done to confirm. My husband and I are very excited even though we wanted to wait 9 months before having our third and final baby. My only worry is I had to have an emergency csection and my scar still hurt from time to time. Has anyone else had babies back to back? Any advice or words would help my worries
