If you mean stretch marks, yes, you can go through 9 months without those. It depends on your heritage, not on creams and ointments you use. If you mean can you go 9 months without your belly sticking out, no.
i agree, you can go through a pregnancy and not have a huge belly, but you will have one for sure, unless your overweight to begin with, sometimes its hard to tell in that situation,
and as for the stretch marks, i only got one (where my belly button was peirced) and i gained 60 + pounds, and i think it has to do somewhat with genetics as well, my mom and my grandmother didnt get them either, (knock on wood, my belly will probably look like a road map now that i said that lol)
