i have had an irregular period since i starting having them at the age of 16. Now that im 22, ive noticed other symtoms such as very frequent urination and increase in apetite. Before i come on my cycle which i only recieve about 3 to 4 times a yr, my breast are very tender. i have been having unprotected sex with my boyfriend for 3yrs now and havent even had a pregnancy scare. i have never been on birth control or any other meds...im confused as to wat is goin on with my body. i also wonder are there any other women in the world that have the same problems as me... i feel so alone and nobody understands :(
