BDSM while pregnant

6 months pregnant and I'm getting back into my sexy groove... when baby isn't jutting his entire body causing some sharp pains that are very distracting...

Anyway, my whole body is much more sensitive in fun and not so fun ways... I already went into shock very quickly pre-pregnancy with all of the.. well, pain. But with pregnancy, I can already tell it'll be that much quicker.. how bad is it if I go into shock while pregnant? A big no-go or doesnt affect baby? Even if I could control the shock enough, would being in that much pain be bad for baby? Am I supposed to avoid pain even if it is wanted and doesnt come with an actual injury? What are the boundaries here?? I miss it now that i finally got my groove back..
