I am 38 weeks pregnant and noticed that my baby had hiccups for the first time (that I noticed) two days ago. Then he had them again last night. I have read that this can be a sign of there being a knot in the umbilical cord.... has anybody experienced hiccups this late in pregnancy before and never noticed them before? This is my first pregnancy so I'm not sure what to expect, and google-ing things makes me paranoid. Thanks!
