16 & Pregnant how do I tell my parents

I’m 16 going to turn 17 in less than 3weeks. I’m pregnant & have held It in till I’ve made myself scared & in tears everytime I ponder on how to tell my mother. My boyfriend & I do have a age gap but my mother & father gave us permission to move out. How ever we are in no huge rush but I kindly thought it’d be better to wait after we were moved in as we already have a place of our own just have about 3-4hrs of work left. My father definitely will not take this news lightly but as my bf mom said what did he expect? My mom is ether gonna take the news okay or very badly which I don’t think she is my problem as I hope she understands how scared me & my bf are. My fear is telling them & me being pregnant already has me scared pants less. Is it also likely the state pick a 6yr age gap. I’m absolutely terrified & scared of the mess I’ve made.
