Episiotomy with swollen vagina?

With my dd several years ago I had to have a episiotomy which I didn't mind really, it took awhile to heal but this time round my vagina is swollen, I'm guessing from the extra blood flow there although I didn't have this with my dd. So today I've got this thought in my head... if i need another and its swollen surely it's going to bleed ALOT and take even longer to heal. So now I'm scared of it happening. Has this happened to anyone?
