Long term birth control??

Tiffany
We have 2 girls and I'm pregnant with a boy and my husband has always said he wants 3 kids but I used to say 4 but now I'm not so sure. I love being prego an feeling baby move but sometimes I just feel like I want this to be our last since we finally have a boy but other times I think maybe we might want another one in several years. So what birth control do yall think I should use?? I've used the pill, shot, nuvaring and had the nexplanon and for some reason I have bad side effects to ALL of them so I'm scared to even Try the Mirena! What bc do yall recommend??
