Can a perfectly healthy woman take fertility treatment to have twins or triplets???

I love kids but Dont want to get pregnant and carry them ... At least not now in my 20s but when I do I want twins and then that's it !... Get it done all at once...after Tubes tied no more BC !

And I always wanted twins

And I should not say perfectly healthy ... They are testing me for pcos or other issues because of my irregular periods but they are saying that I Dont have any fertility issues at the moment ....

... Please be nice ....
