I had my daughter 7 months ago.... I'm not ready for another child. I need to focus on her , establishing her before I have another child. Two years at least is what I'm looking forward to but I don't know if that's in my favor. I feel like I'm pregnant now from how my stomach looks, my sleeping habits, my appetite. Lol I was to go to the gym and work out. But I don't see that because I need to have the time for it. I'm worried. I am on birth control but 99.9% doesn't feel so effective right about now.
