MY MOM FOUND OUT

Gracee
so my mom recently found out that at 15 I lost my virginity and that at one point my period was late and me and my boyfriend were scared I was pregnant (we used protection we were just paranoid) but the way she found out is that SHE READ MY JOURNAL. she decided to let me know she knew by leaving a note on it saying "you shouldn't leave this out if you don't want it read" even though it was in my room on my desk and it's not like she didn't know it was my journal she's the one that bought it for me. what do i even do? should I say something about it?
