I'm sorry for your loss earlier this year. My sister also had a missed miscarriage in January. She knew something was different because she had no symptoms and felt like a million bucks. All her other pregnancies, she was very sick and had tons of symptoms.
I agree with Sara (Oreo). And you can always call your doctor
if something is really bothering you. They want to know
if something is going on. I am also about 6 weeks pregnant. Unless the cramps get worse and is accompanied with heavy bleeding, then you probably are just fine. Take a deep breath! We are here for you.
You should come over to the DD boards!
I wish you a happy and healthy pregnancy!
