I have been having lower abdominal pain on my left side for about three weeks. Overall, it has been a constant dull pressure like pain. I have now been treated for an UTI twice with no changes in the pressure. I have also been checked for kidney stones since I have had them before and I do not have any according to the x-rays. Now my monthly period has not been normal only lasting for around one day compared to usually several days. I do take Apri birth control pill and I am not pregnant. Any ideas or advice? Currently I am trying to get an appointment with my OBGYN to have my ovaries checked, but other than that I am baffled...
