Advice please !

I'm not trying to start a debate on religion. I'm just explaining my situation and I'd like honest input. Again this isn't here to debate whether religion is necessary or not!

I'm 19 and I am a Christian. My family believes in waiting until after marriage to have sex. I believed that for a little bit but then I was like it's my life I'm not going out and killing people (my point is I'm not being bad)

So I lost my V just recently and soon I found out I was pregnant. Initially we used protection. But it got to the point of f*ck it on both his part and my part and we started doing it more often without protection. Which for us was ok because I love him (been dating a year, before he took my V)

We are now expecting and we're both happy but how do we tell my strict Christian parents? He's not a believer neither is his family. So it'll be just my family with the big problem about it. Has anyone ever been though this? How did you tell your parents?
