What to do?

Elaine
So, I was supposed to start my period Sunday/Monday. Still nothing!! I only have very sore breasts and my normal back pain that I've had ever since my back injury in high school. I'm 22... My husband and I have had unprotected sex for 3 years and I've been off birth control for 3 years... I don't want to get my hopes up so I've decided to come here to get another persons insight or point of view. What's the next step I should take?? Any helpful suggestions and advice is welcome! Thank you!!😁😊
