Age 26. I just had my first baby in September. For the past few weeks, I ve had nausea on and off during the day, I ve had discomfort in my right side, sometimes spreading to my left side and back. And recently mabybe 2-3 times in the past 3 or 4 days I ve experienced a heaviness in my chest . I went to the doctor about 2 weeks ago and told me it could be IBS and did blood work but nothing showed up.
