My mother just found out I'm not a virgin

Sooo a couple of days ago my mom was being too curious and went through my phone and found out that my boyfriend was spending the night with me at my college and she kept questioning me on whether I was a Virgin or not. I would her the truth and she started freaking out😳😂 but now she's acting like she's cool with the situation, and it's kinda weird. I am unsure of what to say to her about it. What should I do🤔?
