help needed

i’ve been in a relationship for 6 months and i’ve lost my virginity recently to him. My mother doesn’t like him at all bc he doesn’t have a job or really do well in school. i told my mom about losing my virginity( and being put on birth control) and the first thing she did was threaten to tell my dad and grandma who hold me to a high standard and expect me to wait until i’m married. On top of it all my period is a week late. And mom keeps making remarks that i’m a pregnant teen and my boyfriend is a loser, i wanted my mom to help me and try to make me feel better about the situation and she’s done nothing but make me feel worse. i need advice.
