My husband and I started trying to have a baby last month. Last month my menstral cycle was 1/15. We had sex during the days that I was ovulating and about a few days ago I stared having cramping like I was going to get af, discharge (clear), pulling and tingling in my uterus, nausea, tiny spotting of blood (brown) and back aches. I went to the doctor today and they told me I have a UTI. I have been reading on-line about implantation cramping. Could it also be implanation cramping or just a UTI?
