My baby typically moves at night when I’m laying on the couch or in bed, but I haven’t felt her move at all tonight. This afternoon I did 20 minutes on the elliptical, which I don’t do every day. I’m just concerned that I overdid it. Other than being overweight, I’m relatively healthy. No gestational diabetes, normal blood pressure. I tried to find her with the Doppler but couldn’t seem to pinpoint her. I found the heartbeat for just a second and then it disappeared. Should I be concerned?
