I've been pregnant twice this year and had miscarriages both times around 6-7 weeks. I'm getting my first pregnancy symptoms again, nausea at night, fatigue and very cold. It creates a lot of nervousness because I know it's going to be another miscarriage. I just want to not do anything until I'm past the 7 week hump. Any advise on how to "be"? It's hard to explain. It's like a superstition - I want to have a healthy pregnancy but if I get too excited I know I will be let down.
