Ivf question should I tie my tubes during ivf ?

Ok so I’m being told that I need to tie or remove my tubes permanently if I’m doing

IVF because I have blocked tubes already and there saying my blocked tubes could mess my pregnancy up if I become pregnant should I tie my tubes during my

IVF process I really don’t know what to do and I’m being told I can’t put twins and I’ve been trying to get pregnant for 9 years and finally got the opportunity to do

IVF and they’re saying I can’t put twins when I would rather put twins incase I don’t get this opportunity again

Supposedly they said my tubes fluid could leak to the fetus and cause miscarriage I’m just so confused
