Me and my boyfriend have sex more than 5 times a week. We always use a condom but usually before we have sex we go without for about 5 minutes. My period is pretty regular but lately it has been irregular and this mouth I am 11 days late. I'm constantly eating and always tired lately. Can it be possible that my period is only messing up because of too much sex or may I be pregnant??? If I am pregnant how long should I wait to take a pregnancy test???? SOMEONE PLEASE HELP ME UNDERSTAND WHAT IS GOING ON. So I can stop worrying.
