Hi I'm worried sick . For years I've been having endometriosis type symptoms. Last Saturday I went for an ultrasound and transvaginal where they found a small cyst on my left ovary (3mm) I think and some free fluid in the pouch of Douglas 30mm . The Dr now wants me to do a CA125 blood test which I'm terrified will come back as high and Im so scared it will turn out that my symptoms where actually signs of ovarian cancer . I'm 23 years old and some of my symptoms are painful periods . Pain in lower belly throughout the month usually if stressed or certain foods . Pain sometimes during and after sex . If anyone could help put mind at rest if be very greatful thankyou !
