I had fever and heavy flu during the first week of this month and took some medicines for one ort two days. I had stress for someday as my husband met with an accident. Can these reasons delay my periods. I am 10 days late. I had sex last month during 1st or 2nd and after that normal periods on 12 or 13th June. After that no intimacy. How likely is it that I am pregnant? I am stressed now because I am not prepared. Also I am having leg cramps. But no other symptoms. Sometimes my lower abdomen is paining. But no Periods.
