just relax your self ,the problem is not so hard, in past u were having diarrhea
because of this u might have these symptoms.
since u are having 33weeks pregnancy
so your uterus
is extended to diaphragm so u may have difficulty to breathe, or pain during cough , hurt burn acidity etc.but if ur pain is unbearable , or bleeding so go for ultrasound
for ur satisfaction and fetal well being.
Wish you Good Health
