Hi Ladies, I am a first time mom to be and I am 16 weeks today and was wondering if and when I need to start using any kind of stretch mark cream. In the past my weight fluctuated from normal to overweight (not really fat but got pretty close to it) and now I am a normal weight again, so I used to have a belly at times. Right now my baby bump is growing pretty quickly (probably because I don't have any abs to hold it back lol) but I so far I don't  have any stretch marks. Is it purely a genetic thing or can they be avoided? Do some people never get them at all no matter how big their belly gets during pregnancy? Would those who are overweight have less stretch marks because their skin has already been stretched? I am not too worried about it as pregnancy is a beautiful thing stretchmarks and all it I just thought if there is something I could do to make it better I should at least try.
