Hi Im a 33 yr old mum of 3 children for 3 years I ve been having problems pains where my ovaries are bleeding not when on my periods but light and pains in my tummy I ve been in and out the doctors and they say it s ibs lately with in the last two months the pains have gotten worse it there constantly I went doctors he gave me some tablets for ibs and told me to get a smear but I keep bleeding to I have to put it off I keep having to wee to lately and feel exhausted I can barley eat but manage small meals and I ve put on weight and I sometimes feel like Im going to faint. I was talking to my family and my mum had to have a histmatery at my age and I was an only child. Then on my dads side a lot off women has died at early ages through cancers mainly ovarian and breast cancers the makes where all lung cancers as you can imagine I am slightly worried and I am fed up with the pain and lack off sleep because of it so advice would be most grateful o and the pain is also in my back too
