telling people you're ttc?

My husband and I are ttc our first baby and we are on our 2nd cycle trying. Since we were married in 2015 family and friends have been hassling us about when we are starting a family. It never bothered me before because we weren't trying, but now that we are it does. I don't know how to respond to people sometimes. We have decided not to tell family and friends we are ttc because we don't want even more pressure/expectations from them, we just want to surprise them when it happens. Anyone else in this situation?
