Am scared my baby is dead

Hi,

Please on Saturday I kind of did a lot of work but before Saturday and even until I went to bed I could feel my baby move all day long. But on Sunday until now I can't and haven't felt even a single movement.

Saturday evening and Sunday I had some waist pain and a back ache. I called my doctor and he said those were contractions indicating an abortion. He asked me to take BROCANYL LP. I took the medication and the pains stopped. But up until now I can't and have not felt my baby moved.

Am 16 weeks and 3 days today and was quickly developing a bump. But all of a sudden my numb seems to have dropped... as in not as big as it was on Saturday.

Please can anyone please help me out here? What could be happening!
