Bellafit? Squeem? Actual waist trainer?

This is number 4 for me and I've breastfed all of my babies and IVE NEVER LOST WEIGHT lol I've done natural no medication births...but I've just gained a ton of weight this pregnancy... Idk if it's I'm getting older or what but just gaining sooo much weight! Lol so I used the squeem after my second and third but they are expensive lol I'm planning on getting some high waisted compression leggings but you know just to help after birth and back pain... Idk I just miss my prepregnancy tummy..this I from the weekend we got pregnant...and the next is now lol and I posted this is another group and all anyone told me is to enjoy pregnancy... I do but I'm ready to feel like myself again..
