Plus sized and epidurals

I’m currently 26 weeks pregnant with my second boy. My first son was born by emergency section where I had an epidural and spinal. I’ve struggled to lose the baby weight after my first son (I’m a good 3-4 stone heavier than I was with my first- I’ve managed not to gain any weight so far this pregnancy).

I was wondering if I need another section if anyone knows whether my weight will affect having an epidural or spinal? I’m feeling so nervous about it all! Thanks ☺️
