Ladies! I am so anxious and nervous for my 1st appt for an ultrasound this morning! I am 7 weeks and after this appt, its really going to set in that this is really happening! My husband is going with me so that makes it better but im so nervous. When im anxious I have to poop alot (tmi) and my stomach gets so knotted! Ahh! Just had to let that out
