I'm only 23, but lost my mum to secondary breast cancer when I was 17, and also my cousin to the same thing a couple years ago and she was only 36. Breast cancer is common on my mums side of the family but I was refused testing for the BRCA gene. 
I've now missed 2 periods, and keep having awful bloating and cramps - which is unusual for me as usually my periods pass without any bother. Went to the doctors last week and was asked if I could be pregnant, said possibly but that I had done 6 tests already and all were negative. Did another test in the surgery which was also negative. The doctor basically didn't know what it could be so has now arranged for me to have a blood test just to check it's not pregnancy. However I've discovered a lump just to the side of my cervix, it's soft so I don't think it's a cyst and is about the size of a grape. I'm getting more and more worried, and just wondering if I should go back to my doctor and request a second opinion and also tell them about the lump before having my blood test. Just thinking I could have more blood tests at the same time rather than just texting for pregnancy which I'm 95% certain I'm not! Any opinions would be really welcome x
