Please help scared i have cervical cancer?

im 26 and ive had my first smear test. the results came back and i have abnormal cells and hpv virus. the doctor said im high risk and i have to go to hospital in 2 weeks to be examined and have cells tested and destroyed. im really scared and i can hardly eat or sleep. its all im thinking about. i have 4 kids age 5 and under im really scared. the doctor said if it was cancer they have caught it early enough, but what if they havnt? this is my first smear, what if ive had it since last year? im scared if i have this then i might already have it elswere, i have a sore back, but that maight be because of picking the kids up. and since my birth of last child, hes 5months now. i have still got a small round bump, i heard this is normal, but it looks like im 3months pregnant. im so so scared and i have spoke to the doctor but she says i just need to wait untill ive had my hospital opintment. maybe i have cancer in my ovaries? can they test me for that? im just petrified of dying.
