pussycat I personally don't have pcos but I do have a friend who does have it and did conceive a child naturally. however following the birth of her dd her hormone levels have risen to the extent that her body has gone into premature menopause. she's been told that she likely won't have any more children, she's 27.
I do have another friend who conceived on chlomid and she had twins. apparently she could have more children if she wanted but has no desire to
I think that it's important to remember that every case is different. you will always encounter the people who conceived naturally despite doctors saying they never would, but by the same token there will also be the ones who have to have medical intervention to help them conceive.
Imo you should stay positive but be realistic. Try to relax about ttc, don't time intercourse, make love when you want to, if you are ovulating you could still conceive naturally but in the meantime the medical profession are looking after you and if you don't conceive naturally you're on the first steps to conceiving with some assistance. Relaxing is paramount though, the more you relax about it, the more likely you will conceive naturally, the more you stress, the more ttc will take over your life, and remember that stress can actually delay/prevent ovulation so if there's a chance you might ovulate, it's important to be relaxed to maximize that opportunity.
you know where i am any time if you need to talk, good luck xx
