Dont stress urself out just relax. Stress mental and physical body stress can make ur period irragular even not show up.
Go get a test and take it in the morning when u first use the bathroom, if its false wait another few days to a week to take the second test. If both r false ur obviousely not pregnant.
Ever since i had my youngest my period has been irregular. well I'm a week late for my period but i have been feeling very sick and extremely tired. and i know i had sex on the day i would have ovulated if i had a regular cycle. i mean he does pull out but could there be a chance I am pregnant???? Should i buy a test now or wait until i am a month late to make sure ????
