<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi I have had a dull, mild ache on my lowerwfor 2 weeks. I noticed it one night with a sharp pain in my right shoulder which lasted about 1 hour intense pain then a couple if hours mild pain. I later found out that I was pregnant after 3 urine sample tests but when I went to the clinic a week later they couldn t see anything urine sample came out negative. My period also came. However I still have the same mild ache on my left side. Should I be worried?  <response>: Hello Abdominal pain may be due to many reasons like pelvic pathology, genito-urinary cause, colitis etc. You need proper clinical evaluation and investigations. Basic investigations are routine hologram, urine REME, random blood sugar, renal function test and ultrasound of abdomen. Ultrasound of abdomen can exclude many possibilities. Proper treatment depend upon findings. Get well soon. Take Care Chat Doctor.
