Some of the general factors during pregnancy.
{that I recall anyway - it's been 18 yrs since LOL}
I didn't have RSI/TOS or any health problems back then though.

swelling
increased blood flow
increased weight
increased breast size
looser joints /tendons
balance may be off

well my mind just went blank on any more for that list.

One thing I would really think about , is if things get worse at any time in the future, would you be able get by with possibly only one income or long periods of one income??

And do you have family/friends supportive and close by just in case you need help with the baby in the above scenario.

If your mother, or her sisters had difficult pregnancies or such, or very large babies that might be something to think about too.

But overall barring any complications...I think taking care of a baby and then toddler would be more of a possible "cause factor" than the actual pregnancy..
carrying, meals, laundry picking up the messes....
