I am 9w4d and the only symptom I have is fatigue. That and sleeping seems to be a little more difficult, so the fatigue makes sense to me. But I have been to the doctor, seen the little shrimp and heart beat. They also ran tests and all is great so far. I asked my Mom, she said the only symptom she ever had was fatigue as well.
If u are really worried tell ur doctor about ur symptoms. Doesn't hurt to ask. I got an appointment today because I told them I had no symptoms and I found baby stopped growing a week ago. But please try not to worry as this doesn't always mean the same case for u. I hope ur baby is just fine and everything works out.
