newly diagnosed. not sure if I agree?

Hello, I'm 24 year old woman and last night I got a diagnosis of IBS at a hospital. I guess sort of a diagnosis. The doctor listened to me whine about my cramps then told me it sounded like IBS, and prescribed me Dicyclomine 20mg. He said it should make a difference in a few days and if it does not then I will see a specialist to get an actual, concrete diagnosis.
My problem is I'm reading about IBS and I'm really not sure I agree with his diagnosis.

I really only have two symptoms, which are lower abdominal cramping, and nausea. I was taking a fiber suppliment, mostly because I don't eat a lot and I needed it, and was having normal bowel movements. I've had some minor problems with constipation over the last week, but it's nothing out of the ordinary. No blood, no black stool, no foul odor. Just what feels like a persistent menstrual cramp along the area my uterus is in(sometimes on the left side, sometimes the right, sometimes on both sides). The reason he said IBS is because the pain gradually gets worse, then it subsides back to just a very annoying ache that lingers all day.

Originally I went to the hospital with the concern of an ectopic pregnancy but after a urine test they said I was not pregnant, and that my cramping was IBS. I don't like this medication, dicyclomime, yesterday after taking it I had loose stool and watery diarrhea which is not something I've had since I stopped eating junk food and drinking soda some 2-3 years ago. Also it's making no impact on my cramping, but I'm not sure if it would be helping this early on in treatment.

I haven't been eating any differently than I have been for about a year, and as far as I understand no one in my family has IBS or IBD so I guess I'm just looking for confirmation one way or another, if these persistent, dull cramps, in the reproductive area are normal for IBS or if I should go find another doctor and get a second opinion.

It's never a bad idea to follow through with a second or third opinion and I highly encourage it actually because honestly it's irresponsible IMO for any doc that hasn't performed a colonoscopy on a patient before they come to an IBS diagnosis. Just because you only have 2 symptoms doesn't mean a c-scope isn't a good idea, it's to confirm if they see any inflammation (anyone in the very start of developing an IBD like crohn's or ulcerative colitis could easily have the 2 symptoms you have)...that said, yes, it could very well be IBS.

I actually just came out of a 24 year long crohn's flare that never got into remission once in over 2 decades, around 13 years ago I saw my GI and explained all symptoms and he suspected that I may have also developed IBS as well (which can be fairly common for severe and long flaring IBD patients) long story short, I finally just got out of my crohn's flare for the very first time ever (I should have been ecstatic right! Only I wasn't because I still had frequency and urgency and although for the most part my stools were always formed, I ended up getting badly constipated, I could still "go" of course because I still had urgency and frequency but it was weird and painful) well guess what, it's my IBS that's still interfering in my daily life (so GI was right after all) so I am now in the process of getting my IBS-C sometimes D under control just like Humira put my crohn's in remission.

With my IBS, I also get the same cramps you describe and on rare occasion nausea as well but it's mild, more of a gagging feeling.

You need to get proper tests done to rule out a more serious disease like IBD, diverticulitis, etc because many of those gut diseases can start out the way you're describing your symptoms....not trying to scare you just want to help you get confirmation of what is actually going on so that if it is very serious then you can hopefully nip it in the bud before it blooms into hell and turns your life completely upside down and inside out in all the wrong ways (I speak from experience...I now have to see a therapist to help me deal with all the emotional and mental trauma of becoming sick and staying sick has caused me for almost half my life now) so please get another opinion or 2 to find the root to your symptoms.

Best of luck to you and I hope it's nothing that can't be easily taken care of.

I have a primary doctor I see, and I called to try and get an appointment that day, but the nurse I spoke to told me there was no way, and instructed me to go to the ER. Because I have Tricare prime I don't get to pick who I see. I have a doctor's appointment on Friday morning with my PCP and if this pain persists I'll ask to see an OB. At the hospital I had a culture come back positive for bacterial vagenosis but the doctor at the hospital assured me that was not the culprit of my abdominal cramping.
If I stop taking the medication at this point will there be any side effects? It makes me feel gassy and like I'm about to be sick every time I finish a meal, plus it leaves a nasty, metal taste in my mouth. Yuck.
