My boyfriend's mum

My boyfriend told his mum we were having sex few weeks after I missed my period I told my boyfriend this and on Sunday I was over at their house I told his mum and she came back with a pregnancy test and a glass and told me to pee in it I was sooo in embarrass with it . It was with him ,his mum and his mums friend. I did what she said to do and I wasn't pregnant thank goodness she told me it was probably stress why I didn't get my period. I never told my mum and am scared to tell her am having sex at 14 and my boyfriend is 15👀I love him so much and I know he loves me. I guess you could say he more content with telling me loving thing then I am with telling him but I try to I just get the butterfly in my stomach.😅😖
