How do you find the time to...

I've recently had a baby girl on January 17th, 2015. 🎀🎀🎀
I've been married for a year and a half now and everything has been going really well... Keeping very busy with our new baby but... Me and my hubby still haven't had sex yet because of complications after I gave birth to my daughter(all good now!) and body issues I was having after getting pregnant. 
Also, while I was pregnant we barely had sex earlier as I was always too tired or sick or not feeling well. 
My husband thinks it's unfair but I feel like I need time to get back in shape and feel confident again before I enter that world again. 
Has anyone ever gone through this? Am I the worst wife ever? Please help.Â
