I just started getting this weird tinkling/tingling feeling towards/at the end of peeing almost like the feeling you get when have sex exact it goes away right after I pee. I've never had tis feeling before. My doctor did a blood pregnancy about a week ago and it was negative and my urine was negative for infections. I have blood clots and am on blood thinners so I cannot drink cranberry juice or anything with cranberries. Also I'm allergic to penicillin so can't have any of that My biggest concern is I went to my doctors a week ago (mon) and they didn't feel my paraguard strings and I have sex that Sat and Sunday before my appt. I got blood test and it came back negative. I was told not to worry since the strings prob shorter and they would do ultrasound. Then on the 17th-19th I had sex believing the paraguard was in place. We'll surprise to me I went to doctor on 20th for ultrasound and the Paraguard is nowhere to be found. And we don't know when it came out. Please help with these two concerns
