i am 18 years old, turning 19 in a week and i have serious doubts on my ability to get pregnant. i know im young and im not planning on having kids for a while but i still have some concerns. i have an irregular period, i can go more than three months without getting one. ive been that way since i first started it. the doctors told me that it was normal because i played sports and i was really active. but i havent been active at all since i graduated high school in june of 2008. and its still the same. im sexually active with my boyfriend and at first we used protection (condoms) but now we dont use anything. i know its not him because he has a kid already with another girl. theres nothing that i want more than a baby...one day but whats happening now is really getting to me. i want to know if something is wrong with me because i know that there are some women out there that have problems with their ovarys and being infertile. i pray to God im not one of those women. nothing like that runs in my family so i just want to know what is up!!!
