Having a white discharge is common in pregnancy
unless it is watery, profuse or foul smelling associated with itching or bleeding. Heart burn is caused by the stomach being pressed due to the enlarging uterus
. If you feel tightening of the abdomen along with pain in the back or groins with decreased fetal movements, it is time for concern. The impact of your previous caesarean delivery depends on the cause of that surgery, the time lapse since and the progress of the present pregnancy. Please proceed as you had planned and get a second opinion
at the earliest. Wish you safe motherhood.
