pregnant and happy

When i found out that my monthly period is not yet coming about 1week delayed. I tried a pregnancy test immediately. I was surprised and ofcourse happy that i am blessed with this baby but then im kinda scared to tell it to my parents my mom and dad. I'm actually 25 and a first time soon to be mommy. I know i'm already at the right age to have a baby amd build my own family but still i feel like scared to tell this to my mom and dad , the fact that i'm the eldest  among my 2 sisters. I'll be the first one to give them grandchild. I maybe afraid of the negative  stuffs they will say . I am planning to tell it to my mom first after i see OB gyne tomorrow morning. Well. . Wish me luck and i need courage to say it ,after all we will all going to ne mom and they have to understand it 😝😋
