I feel your pain! I'm 21 and me and my partner are TTC but im scared to tell my parents! I know my mum is just waiting for the "Im pregnant" call and she would be thrilled i think but for some reason i feel i cant tell her im trying as i dont want the "you're too young...you've got your whole life ahead of you" speech. Id much rather have them think it was an accident which is really sad!! But congrats on the pregnancy, im sure once they see that little bundle of joy all doubts will be forgotten!
