hi. good day. i was wondering if i have this ovarian cyst . because when i had my ultra sound last year around (december or just this year january2011). my ob saw that there could be a cyst in my ovary . i had my d&c before because of miscarriage . and after that, i had my one irregular menstruation. i had sex with my boyfriend when i was having my period. and it was unprotected. sometimes, it is painful. i also felt lower abdominal pain before. i am confuse if i am pregnant or i am just having a delayed menstruation. my first day was April 17, 2011. but today is may 18,2011 and it is still not coming out. i had my pregnancy test yesterday may 17. and it turned to be negative. please help. i want to know if i am pregnant or i have this ovarian cyst. thanks.
