missed period after first time?

Here's my opinion, having PMS and losing your virginity has no connection at all,the blood you see was only an indication that you lose your virginity, if you had an unprotected sex, you should undergo the so- called pregnancy test..at least after a week...you are responsible for knowing your cycle and when you could have safe sex and time you couldn't.. GOOD LUCK!!! :-)

A lot of girls seem to have there periods a bit early or a bit late after first time sex. If you had unprotected sex, was it around 10-16 days before your period was due? Since you are late for your period, you can take a test now.
