Hi, I am a 25 years old unmarried female. I have been having watery loose motions (diarrhoea) for the past 4 days, along with nausea and unnecessary headache and lower backache. I have also been taking medicines like norflox 400 and zintec but it's not helping. Everytime I eat anything, I usually have to rush to the washroom. I google my symptoms and somehow I came across lots of articles which indicated that I might be pregnant. That these symptoms might be of early pregnancy. I last had unprotected intercourse with my fianc� on 5th August after which I took an ipill. My dates are usually within the span of 18th-21st days of the month. On the 4th day of the diarrhoea I experienced some spotting too, and I thought that my date came early this month but these spotting were irregular not like periods. I even took a pregnancy test, and it was negative. I am still unsure what is it that's happening. Request you to advice and help me out of this dilemma and discomfort.
