more twins because of swaying?

I was just wondering. is swaying increasing your chances on twins?
I see a high lvl on twin pregnancys here.
I've been reading in on what causes more twins and if I interpreted it correctly its a chance in estrogen lvl's wich increases chances on twins.

I'm wondering if it's because a few of the ladies who had been swaying were taking Clomid or similar which seems to increase the chances of twins. That, or went via the IVF route, maybe?

Virtually everyone who got twins on here was on Clomid. We have not had many naturally conceived twins at all.

Ok! I was just wondering! Thx
