My period has been late for about 9 days now. Actually my period has been irregular ever since I got married (late November last year). But 9 days late is considered a record for me. Since this year, at most my period has been late is 5 days. I did take a pregnancy test (ClearBlue brand) on a day ago (in the morning) and it came out negative. Unsatisfied, I went to the doctor whom took a urine test (which looks rather 'cheap' compared to the one I'd used). It came out negative.
