Your symptoms suggest that you have began to get into pre-labor
and the spotting is the cervical show. As you have already had two babies, your cervix
may dilate in no time and it is essential that you get yourself examined by a consultant at the earliest possible. The decline in fetal movements could well be due to the fixation of the presenting part. Please avoid solid food, take plenty of liquid diet
and get proper care at the earliest. Wish you safe motherhood.
