C-section and vaginal birth question.

So I just had my son in January via c-section. He’s already going to be 8 months in a couple of days, and I found out I’m 5.4 weeks pregnant. My doctor is telling me I’m going to need to have another c-section, and that vaginal birth is a slight chance since I didn’t have a year break in between pregnancies. I feel as I’m not given a choice of what I want to do. Is it true that I’m not able to do vaginal after c-section for this pregnancy? I have nothing against c-sections as because I’ve gotten one but it was really no choice for me because my son was breeched. I just really want to try to do vaginal if it is possible, can anyone give me an insight with experience?
