Hi.. My husband and I are trying to conceive.. For the past couple of days, I have been passing hot urine (like when you run a mild fever) .. Today morning I had a bad case of diarrhea .. I sometimes feel a heaviness in my lower abdomen, with a mild dull ache at times in my lower right abdomen. No other apparent pregnancy symptoms have been experienced. I had UTI last month. Also, does sexual intercourse trigger UTI? I got my UTI 2 days after intercourse. Age: 29, Weight: 50 - 51 kilos, height : 5.2 Thanks.
