I've had 5 sessions now and I LOVE it, my accupuncturist made me feel really at ease right from word go, not only do I get the accupuncture but he is also reallly easy to talk to, knows alot about dietry stuff to help with my pcos, and throws in other bits and pieces to think about as well. I've noticed a massive difference already in how I'm feeling and how my body reacts to different things.
It's also very relaxing, doens't hurt, and its really not like what you imagine when you think of 'needles'. the ones he uses are sooo thin, they are almost just like stiff thread!! That's how fine they are, they're not sharp or stingy and shouldn't ever be, it's more 'crampy' or 'achey'. I really would recommend it.
Just make sure you get someone who is experienced in fertility accupuncture as well though as there are some points that should/shouldn't be used depending on where in your cycle you are.
