I was just wondering...I have been having major headaches almost eveyday with this pregnancy. I didnt have that at all with ds but I dont know if these headaches are from the hormones or what. I upped my water intake to almost a gallon a day, but still have them. I do have a cold, but had the headaches even before that so...I dont know I just thought I would check and see if this was just a twin preg. thing. Also having lots of cramping at only 16 wks, but since I upped my water it hasnt been as much. I just cant help worrying. I feel like everyday there is something new going on in my body, and it is soooo different than when I was pregnant with only one. When I first found out that we were having twins, I just freaked, but the thought of something happening to one of them now makes me worry so much.
