[|Human|] I had sex with my fiancee on17 October,2015,a day before my menses could start on 18th October, 2015. I experienced delayed menses on 21st October,2015. But for this month November, 2015 there seem to be nothing yet. What could be the cause to this delay? Am 21 yes old.Thanks
[|AI|]  Hi, I have read your query & understand your concern.  Though the common cause of delayed periods is pregnancy, specially n child bearing age. You had delayed menses after the sex in question & also sex was just 1 day prior to menses. So there was no possibility of pregnancy that it.  You had no period till the date in following month (November)too & it can be due to- - Pregnancy (if you had sex in the cycle- to be excluded by home pregnancy test.  - Severe weakness/ anemia - excessive physical or psychological stress - Hormonal imbalance like in POD/ thyroid problem/ ovarian problem.  These conditions can be investigated by pregnancy test/USG lower abdomen/ hormonal assay, /thyroid function test./ CBC... followed by specific treatment.  Thanks.
