I am becoming worried. I am a first time mother and am 11weeks. I have an ultra sound here in a week but I just can't wait and would really like some input. My symptoms have started to go away such as nausea and breast tenderness. My back has been killing me. It's a really sharp pain in my lower left side that goes all the way into my legs. I started to read about back pain during early pregnancy online and I got a lot of stuff about miscarriage. I would hate if anything bad happened but I just can't help but to worry even though I heard the heart beat last week.
