How much cramping is normal?

Hannah
So this past week I've been having more shooting pains and cramping pains in lower abdomen. Like really low, so thought it was the round ligament pain. Also cramping if I don't drink enough water. But now much is too much and how much is normal? Seems like it has been multiple times a day this week. First time mom-to-be here and about 15 wks. Thanks!!
