First time mama!

My husband and I have been trying for 3 years I’ve done all the IUIs and medicated cycles I can. We had just scheduled IVF for February. I found out right before my missed period that we are expecting. I’m a nervous wreck, it took so long I’m anxious about miscarrying. I am 5 weeks along my test have gotten stronger every day and I really only have sore breast and gas consistently. My first OB appointment is at 6w5d I’m hoping that they will do an ultrasound but I’m not sure if they will. Any encouragement you can send my way?
