I want to make the last couple months of my pregnancy special

My mom doesn't have any keepsakes from when she was pregnant and she says that's her biggest regret. I want to collect as much as possible to always have the moments saved. The only thing is this stuff is expensive. I want to do a 3D session, get a heart beat teddy bear, take maternity pics and get a pregnancy massage. The massage thing is totally for my sanity lol. I'm contemplating just doing some homemade maternity pics so I can have extra money for his newborn pics. I'm a first time mom and didn't think about any of this stuff til right now. Are there any experienced mamas that have done or not done some of the things I listed?
