How to keep weight on after delivery??

I don't really know where to put this post, since I haven't been really on eve since finding out I was pregnant. I'm on my second baby, and with my first, I lost all my baby weight within two weeks after delivering my daughter. I prayed that some of the weight would stay on (I usually stay between 105-110 lbs) but again all the weight just went poof 🥺. I maintained the same eating habits with my daughter but I was also breastfeeding which my doc said contributed to some of my rapid weight loss. But, due to medical and personal reasons I will not be breastfeeding this time around. I just wanted to know maybe there are mamas on here that experience the same thing and maybe someone out there can help me. I hate how tiny I am pre-pregnancy. I just hope someone can help me because my due date is only a month and a half away and I just wanna feel like a real woman for once 😭
