Baby on the way! Right time to say

I have taken 4 pregnancy tests now and all say I'm positive. My boyfriend and I have been dating for over a year!! We live together and everything but we don't know when we should tell our families because we both agree they won't accept that we are pregnant because we have been dating for that short period of time. We live together and are on our own before even. Both our family's love each other. But idk when the right time is... help!?
