I would follow the doctor's suggestion, with the pain coming and going you are always going to wonder if there is anything wrong. There could be a number of issues, probably a gastroenterologist could quickly rule out couple of things by just pressing on your belly on different locations and by questioning you about your symptoms, also running some blood test. If you had abdominal surgery scar tissues can form and can be a major source of pain unfortunately. So examination, blood work, imaging is a possible way to go, especially if you have these symptoms for a while. I have had all of the above, symptoms, tests, nothing was found, still have stomach aches (no other gastro symptom/no problem with digestion/elimination just pain) stress believed to be the reason of my pain, nothing really helps, warm bath, relaxation.
In your case also a gynecologist visit could be beneficial, just to let them know about your pain.

I get bad stomach pains too

I get pains like that when IBS hits me like the trainwreck it is. Sometimes it means IBS is forthcoming, other times it's just there to make me suffer, I swear. Get tests done anyway, better it be nothing than you find out later down the line it's something serious. I just had an MRI because my lower half is attempting murder. It could just be Fibromyalgia trying to tear me apart - or - it could be my stupid spine doing its best to fall apart.

You never know until you've done due diligence.

Take care of yourself, lady. (And happy birthday, btw) xx

Ive had the exact same. At 21 I’ve been diagnosed with endometriosis. I had my second laproscopy last year to check on these pains which sound very similar to what you describe, I was told this is not due to my endometriosis and told to take the contraceptive pill without having breaks for 6 months. Even though I have done this I still continue to have the same pain. I have been told I have IBS but this pain definitely feels like gyne pains rather than gastro.

Could be irritable bowel syndrome, could be adhesions [scar tissue] or something else. I recommend the cat scan
