Professional Maternity Photos or DIY?

To

Did you get pro maternity photos or did you DIY? My first pregnancy I never did any special pictures and this is probably my last one so I really want some special photos. Is it worth it to pay a pro or easy enough to have a family member or friend do it yourself? If you did a DIY what kind of camera did you use or did you just use a phone camera and how did they turn out? Also what is the usual time in pregnancy most women have theirs done?
