Sorry for TMI but my son has been kicking around a lot for the past hour or so and I just got random sharp pains in my hoo ha. The first pain was kinda like a tickling feeling from my tummy to my hoo ha and after that I got 3 more sharp pains kinda in a pulsing order prob about 30seconds to a minute from each other and then they stopped. Should I be worried? I'm only 31w
