Hyoscyamine Sulfate 0.125 mg

I have been taking hyoscyamine sulfate 0.125 mg x's 2 for about 15 years, for bladder incontinence. When I was able to get a generic tablet, my pharmacy supplied them. The tabs I received in my last prescription were different - larger with numbers & insignia that I was unfamiliar with. Since my pharmacy changes pharmaceutical companies from time to time, I didn't question the change. In the last 2 weeks, I have had an increase in bladder incontinence, including some pain/discomfort. I had the prescription refilled & the tablets are the ones I have previously taken. I then went over the prescription labels & find that although the pills are different, the manufacturer is listed as the same - all other information is the same.

How can I find out what pill I received last refill & if I was given the wrong medication - therefore causing me to have a reoccurrance of symptoms. I am contacting my pharmacy on this matter as well.
