Okay - so my GP now thinks I have PCOS due to funny periods, bad period pain, heavy periods, mood swings and acne! Lovely - but she has reffered me for an ultrasound to check for it, what is an ultrasound? She said for women who've had sex they have an internal one but due to the fact that I'm a virgin (at 19 - the shame ) she says I'll need to have it on my tummy as it would hurt too much seemingly...? I've also got to get a fasting blood test, with nothing to eat or drink (other than water) for twelve hours - I hate needles, and I'm worried I'll collapse, if I do will I be OK? Even thinking about it makes me feel funny, and I know it'll be more likely if I haven't eaten what if I collapse on the bus whilst going up there? Aargh. Help please hehe?
