Can uti cause a strange feeling in lower tummy and groin area?

Yes. Usually a UTI will give you burning when you urinate, an urgency to urinate, and frequency of urination. It can also cause an aching or cramping in your lower abdomen or groin. Other causes of pain could be an STD, constipation, ovarian pain, menstrual cramps, etc. I would get a urine test at your PCP or an urgent care to know for sure.
