I talked to my Dr office then went to the birthing center. I'm 20 weeks, they didn't do much, just watched for contractions and used a Doppler. It gave me peace of mind. Then baby went back to being crazy... Murphy's law I guess :)
I started to feel movements at 16 weeks, and at 17 the first kick. I didn't feel anything else until few days when I started the 20th week. Now my baby is no stop lol this is my first baby. Anyway I think you shouldn't worry, it's still early. Just ask to your doctor if you are still worried about it!
It is hard to say. I started feeling movement with my 2nd child when I was 10 weeks prego. I felt movement until I was 15 weeks and then the movement stopped. I was freaking out as my previous pregnancy resulted in a miscarriage. I went to my doctor and he did an ultrasound and everything was just fine. My doctor said that sometimes, when you feel movement early, you don't feel it later because the baby is in a different position and 16 weeks is pretty early for a lot of women. You're baby is probably just fine but you should talk to your doctor if you're concerned.
