hi i have completly missed my period for october last period was on the 1st of september very normal no worries and when it didn't show up in first week of october my first thing was i'm pregnant so went out and brought two test took them on two different days 5 days apart both were negative so didn't really worry too much excpet for when i started to get low abdominal pain went straigh to doc to which he did a test an again negitive but got me to do a blood test as well which also came back negitive doc told me to come back in a week if still had pain. so i did which now made me 3 weeks late he got me to get a ultra sound i got an internal one done and all they found was a little bit of fluid on my right ovary. i went back to doc and he gave me another blood test and gave me some anti immflammortories. blood test again came back negative and now pain has gone its been 4 weeks tomorrow that i'm late doc doesn't seemed to concerned but main reason why i'm worried is i am on the pill am very consistant with the pill every day same time and always very regular with my period so i am wondering why now i haven't change my diet or exercise or job am not under any more stress then usual and am just concerned and wondering if any other women has gone through this and what was their outcome. thank you for taking the time to read my post
