Could you be pregnant if you have had stomach cramps some nausea the bottom of your stomach hurt like your muscles been pulled your period might be late but they are not very regular but same for 5 mo?

I think that if your period is late 5 months (ie. it is 5months since your last menstruation), and you are not in your 40's or more and you do not use some kind of hormonal therapy -like birth control pills- which could interfere with your menstruational cycle, I would advice you to take a pregnancy test. if the pregnancy test is negative, and you didn't reach menopause, and you did not take any form for prescription medicine AND you haven't had a period for five months; you should go see your family doc'/GP.
