Consider me in your corner as a fellow sufferer of similar complications. I have been doing the daily enemas, too, after trying every medication anyone suggested. Things that are supposed to fix constipation seem to only increase my pain without inducing BMs in a reasonable period of time (I can't wait many days or the gas pain becomes unbearable). For me the daily enema has been the best of bad options. If you could scale back on work at least temporarily that might help a lot. I find doing the enema on a deadline is a problem. If I rush, the results aren't good, and I'm usually in "recuperation mode" for at 45 minutes or so after ward where having to stand continuously is very uncomfortable. I wish you all the best with your pregnancy and your own health!
