couple days ago i started getting some pain in my abdominal area. it was very mild on the beggining but now it kind of got a little bit stronger. it's kind of a slow node pain that comes every 2-3 minutes. the area of pain is on the left side on the same level position as belly button. my period was kind of different for the last 2 month. month before last one it was very light but it lasted for 3 weeks. and the last one was very light too but it lasted for 3 days. i went to the doctor and she said that everything is fine. but now i started to have this pain and was wondering if they relate to each other? is it something serious that i should be conserned about it? what possibly could it be?
thank you very much
