Can you use a rebounder whilst pregnant?

[lilibet]

I was watching 'Knocked up' last night and it was mentioned that you can't trampoline whilst pregnant.

I love my rebounder and am TTC, will be distraught if I have to give it up as it's one of the only things I can do - I have dodgy knees and am not a good swimmer.

It seems strange that you can to runnign but not bounce?

Have googled but can't find anything, does anyone know anything?

Film was vastly overated BTW!

don't think its a good idea, especially if you have dodgy knees already. due to all the hormones all the joints weaken and things become looser, mums find they're much more flexible whilst pregnant so you may injure yoursself
