tell my mum I've lost my virginity or nah?

I'm 17. I lost my virginity 1month and 10 days ago to my boyfriend. We have been going out since October but have always had feeling for each other since year 8 , so we're close. My mum and family know about us, so does his. BUT the big question is should I tell my mum I've lost it or not?? She's spoken to me about it and said whenever I do it use a condom but I say I'm not stupid and laugh about it😂😂Help????
