7yr 6months my first baby was born n my wife was on contraceptive pill n its been nearly 13months she gave up pills but having problem getting conceiv?

Listen to body: Some times periods don't resume right away after being on bc pills. Check vaginal mucous daily and if it strings out between the thumb and finger she is about to ovulate and fertile. If the mucous doesn't string out, make sure 25-oh vit d3 levels is normal. No alcohol or tobacco, a healthy diet, good night sleep, regular exercise, and good stress management will promote health.
