That me and my boyfriend are expecting a baby?

I'm four weeks along and it WAS NOT planned.

I just recently moved down to FLORIDA from NY to be with my boyfriend of 7 months. We have known eachother for five years now but only in the past 7 months have officially started a relationship.

So... we are very excited and happy to be going through this journey but are also really nervous. Because he/she wasn't planned.

So how do I tell my mom, the woman who has told me hundreds of times that she doesn't want to be a grandmother at 41 years old (im about to be 21) and who has given me very very high expectations on what she expects from me...

Im scared shitless to say the least, not about becoming a mom (my goals in life are to be a mom and wife) but about telling my own mother.

Not telling her isn't an option because I'm still on her insurance because I'm a student under 25 years old.
