Hello, Yesterday and today I have been having sharp pains in my abdomen. I seem to feel more discomfort on the lower left side. I ve been on my period but this never is an issue. I do tend to have heavy periods with back pain and bloating but not the sharp pains in abdomen that come and go and especially not all the gas. I have had quite a lot of discomforting gas and two times felt a little sharp pain on the right side of my chest (under the breast) which was yesterday afternoon and early this evening. I am wondering if I might have a urinary tract infection and if this would cause the gas and such? I had sex before my period and was sore for a couple of days and urinating a lot. Its fairly tender towards the lower abdomen which is strange because I am towards the end of my period. What do you think? Also it s interesting that before yesterday I was eating very healthy-lots of fresh veggies and fruits/grains. Then yesterday was a whole day of eating sushi, indian food, etcc heavier foods. Maybe its a problem with my period? Thanks very much for your time!
