Hi dear. I am your physician, having a vast years long experience in the field of General Surgery, psychiatry, Radiotherapy, OB/GYN, Internal Medicine, Ottorhinolaryngology and Nutrition and weight loss, and Pain Management. I have carefully gone through your case and in my expert opinion there is nothing wrong & u need not to worry. Pregnancies go differently everytime even with the same woman. U see sometimes its C section(due to breech presentation of baby) and the other times its normal vaginal delivery to a single woman. The symptoms u are facing are due solely to compression of nerves and blood vessels. Stomach being upset and pain in epigastric region(almost to middle of abdomen little above the umbilicus) happens in pregnancy due to upward push on Respiratory muscle(diaphragm) and that makes the food pipe less tight on its lower Sphincter. Thats why stomach acid comes into food pipe(esophagus) and heart burn or stomach pain is felt by pregnant women. My reassurance to u is that u need to relax and keep calm for whole of ur remaining pregnancy and I hope u get through it with a healthy baby. Thanks for trusting me, stay blessed !!! Dr. Hanif
