Thanks for the query.
regurgitation of food contents can be seen and sometimes it presents as heart burn.
But better consult gynecologist and get examined to rule out other serious causes.
If she suggests you can go for complete blood picture and ECG.
If everything is normal, no need to worry.
Taking plenty of water, timely food, antacids can relieve the pain to some extent.
