Frequent urination and pregnancy. Uti?

So exactly one month ago, me and my bf did some dry humping with clothes on. He ejaculated on my pants but cleaned it with tissues right after. After some minutes he started fingering me, he didn't enter the vaginal hole but he rubbed on the clitoris. My period ended on october 12th and this happened on oct 15th. I also have pcos and on nov 6th i had scanty period for 5 days with brown and red color bleeding with clots which is more than spotting and less than heavy or medium flow. Yesterday i went for a regular checkup and they did an ultrasound whole abdomen. I will be attaching my scan report. And from yesterday i have been peeing very frequently there's this slight discomfort near my urethra.Is there a chance of me being pregnant?? or I am having any UTI?? I haven't done any tests yet.
