I had both done and I am also petrified of needles and blood tests
But, it is over so quickly.
Just make sure you eat and drink before you go and take something sugary with you in case you feel faint.
Whenever I do for bloods, I always tell the nurse and they are super with me.
Don’t be scared, just think of the outcome. These things need answers and you never know, you could be fine and everything come back normal!!
Just a little heads up, if they check your hormone levels, ask for a print out and do some research into normal/abnormal levels. They told me a few years ago I was fine when I clearly wasn’t. I only got diagnosed last year after fighting for 10 years
then I had to go private and my gynaecologist broke the news to me!
Good luck
