I will definitely let you know, Village. One of the studies I was reading said that the average American consumed around 5g of l-arginine a day, and therefore for their research they supplemented with over 6g, so 100g in Pregnacare is a very small token gesture.
I feel fine, thanks. No pregnancy symptoms on pred but I do have very bad shakes in my hands and in my face which I'm also going to ask Mr S about. I posted on here about my shakes about 6 months ago, and I was referred to a neurologist by my GP, but by the time my appointment came through, I cancelled it because I thought I'd worked out it was caffeine. They almost disappeared when I stopped drinking coffee. However, I now think it may be pred as well as caffeine.
My belly is enormous too, after a week! A child at a party we went to this afternoon asked if there was a baby in my tummy ... It's all worth it if it works of course, but when it doesn't and you're left with the aftermath of constantly looking 4 months pregnant, it does get you down.
It took me 9 months to get pregnant again, Village, so hopefully it will happen for you very soon.
