Bladder, or intestines?

So I was on vacation 10 days ago, and started to have stabbing pains in the pelvic area, just above the pubic bone. So I thought that it was the beginning of a bladder infection, so I got some Cipro( which usually takes it right away). But nothing changed the pain continued. When I got back to canada, I went to emergency, 5 days ago, and after urine ysis found out that it is not a bladder infection. I went for an ultrasound of bladder and an intral ultrasound. Everything was normal. Had another appointment with Gyno, yesterday, told me everything is ok with uterus and ovaries .So now he says it has to be the intestines. So I am asking: would pelvic pain (right above pubic bone) really be related to gastric track? I have pain sitting, walking, and when I sit down I get a sharp pain too. Without wanting to sound too graphic it hurts when I p stool or gas...... anyone have any clues? I am supposed to see a gastrointerologist in 2 days.I am taking empracet for now for the pain.
