I've had horrible problems with constipation throughout pregnancy up until about 2 weeks ago and now everything is just great. My toilet and I are on speaking terms again. I have no idea why. Maybe that often-heard "baby dropping?" Less pressure on the intestines? Those magnesium tablets I started popping a few weeks ago like they were ecstasy (How can 4000 mg of magnesium be bad)? Hormones for pre-birth? UFOs? Why am I speaking to my toilet?
And that is your not-very-scientific medical minute, brought to you by flyingspaghettimama. So I'm not sure it's pre-labor relief that you are experiencing, although thank goodness it's happened, huh?
