It is very normal to cramp throughout pregnancy. Try tylenol. If it gets severe and you start bleeding then go to the ER.
I've been woken up by them too! They've lasted for hours before. Sit up, drink water. Take Tylenol if you need it. :) It's just your uterus stretching and growing. Kinda hurts lol You only need to worry if you bleed, or if they are soooooo bad you feel something is off. I mean I had bad menstrual cramps my whole life, to the point where I laid down and cried, so I was able to lay there and endure fairly bad cramps without meds and wasn't even concerned. Looking back I found it odd lol. I wasn't even concerned enough to call my mom. But yeah, totally normal. Water, watch TV, rest. You'll probably be sore in your uterus area later/tomorrow lol
