Urine will normally be darker after a night of sleep and lighter during the day because of intake of fluids. And meds make a difference too.
Your doctor is watching this so that's a good thing, but it may not be a bad idea to contact your GI. Sometimes meds have to be adjusted. I'm assuming your Gyn. knows about your meds, but honestly, many doctors who aren't familiar with IBD treatment will not know about these drugs' side effects or symptoms of this disease; at least that's my experience.
Just keep your fluid intake going. Hope all will be okay.
