Newbie - Well, kind of it's been a while

A little about myself...I'm 42 and I think I mentioned I already have a beautiful dd who is 6. I lost an ovary at 18, so I'm already down by one...but a couple of years ago the doc told me I've got the hormones of a 20 year old. I've always wanted more children but dh has been hesitant until recently. To be honest he was always a no, and then one day he asked if I still wanted to have another...you can guess my answer! :) So, we'll try, but I don't want to totally stress about it if it doesn't happen. Sometimes reading articles on having children in your 40s is disturbing...I've gotten pg 2x, but lost the 1st one at 12wks. I'm doing all of the stuff I did last time...charting bbt and cm. I'm taking prenatals already and vitamin d. That's about it...I seriously don't think it'll happen the first month of trying, but I guess who knows. Hope everyone has a great weekend.!
