-I took it in order to sway pink, and got pregnant on my first cycle trying. I have a history of repeat miscarriage, and my RE prescribed it almost as an afterthought while I was on the way out the door--that is, it was extremely easy to convince him to let me try it. I do have a history of borderline/low progesterone, so there was arguably some medical reason for me to take it. I don't know that he would have given it to me if I'd said that I really only wanted it for swaying pink.
It did have some nasty side effects, which surprised me since I was on a low dose (25 mg). But I had nausea, hot flashes, awful ovulatory pain and was very dry when DTD (so much so that DH had trouble finishing--this had NEVER been a problem before). I am thin, and side effect severity does tend to be correlated with weight--someone who weighs more can take a higher dose with fewer side effects.
Many doctors will prescribe it readily. It's cheap, it's been around a long time, and it has a long history of being relatively safe (which isn't to say it's always safe--it's safer in lower doses, and safest of all with monitoring). You can always say that you've been tracking your cycles and have noticed that they're irregular, and/or that your luteal phase seems short. I did not mention that I wanted it to sway, and I did not mention that I am still breastfeeding my toddler (to be honest, I think the RE forgot to ask). If I were you, I'd probably just say: "I'd like to try it to see if it will help me ovulate regularly."
It does increase your risks of multiples (though by how much can vary depending on when in your cycle you take it), so it's important to think about how you'd feel about this. (I did not want twins, and luckily, have only one). It also can decrease your chances of getting pregnant. I was shocked that I got pregnant when I did, just because the dryness seemed so hostile to fertility. (I was hoping to do HT, and was ambivalent about whether or not I wanted to get pg on that cycle at all. We weren't trying all that hard).
On the whole, though, I'd go for it if I wanted the best possible sway and couldn't afford or wasn't willing to do HT. It *has* been scientifically proven in good, well-controlled studies to sway pink, and so much of what we do to sway has far less proof behind it. But it sways, it doesn't guarantee. That is, it raises your chances from 50/50 (or what it really is, 105 boys per 100 girls) to something like 56/44 in favor of pink. So while it doesn't guarantee you pink, it does give you better chances, and in my opinion probably raises your chances more than many other sway tactics. Your best chances of all, in my opinion, are adding Clomid to an otherwise good sway (with diet, exercise, etc).
Anyway, I don't yet know what I'm having (and we'll see if I even make it through the first trimester with a live fetus--I've had enough losses to feel pretty cynical about this), but I can let you know once I find out.
Good luck!
