Pregnant too soon?

So my boyfriend popped holes in the condoms, and I just found out. Because he wants us to have more kids...

I’m only 4mos PP. I had a emergency csection... ive been breastfeeding, and haven’t had a period yet.

If I were to get pregnant rn, would I be able to vbac? I’m so scared, and nervous that I won’t be able to if I do get pregnant.
