Early on in pregnancy, large amounts of the hormones relaxin and progesterone are at work, relaxing the muscles in your body — including those in your gastrointestinal tract. This makes food move more slowly (good for baby) but can lead to indigestion and gassiness for you (bad for anyone standing, sitting, or sleeping near you). In addition, your expanding uterus places increasing pressure on your rectum, which can wreak havoc on muscle control and lead to the passing of some serious wind.
PS. Still laughing!
