Vbac worries

I wanted to know if there was any women who have experience a vback with their second pregnancy. I found out I was pregnant again when my daughter was 15 months. That's a story in itself haha but has anyone ever had a successful vbac in a shorter time. I'm trying not to freak myself out. I'm sue on the 8th of September and my daughter turns to on the 26th of September. My Dr. Say I have a good chance. But idk I'm so worried about the rupture that I think I'm making myself scared and trying to get out of it. Thanks again.
