Hi, Its 14th day post iui. Last period date is 30th December.  From last 3 days  I am feeling left side abdominal cramps. Its not unbearable but feeling uncomfortable while walking or having normal casual moments. Sometimes i also feel same on right side. Its not constantly paining. Mild cramps are there with little white discharge. I did not experience any implantation bleeding or other symptoms. I am also experiencing constipation from last 2 days and overall feeling very dull. Are these pregnancy signs? I am worried why i did not see implantation bleeding yet?
