Hello my name is erykah I am 20yrs old and my last period was 5-29-11 and was not normal. I only had period blood when I wiped. It normally last for 4 day and only last for 2.. This month my period was supposed to start 6-37-11 however it has not come and I am now 3 days late. I have no pregnancy sympthoms but for 5 days I have been very emotional.. I would just cry for no reason. My stomach is in horrible knots some times but not all the time. I get sharp pains only for a second in my lower bell and my stomach just burns.. what is wrong with me??
