Caught having sex

Today my boyfriend and I were home alone and things started getting heated. We ended up having sex and midway through, my mom came home. She didn't see anything, but she heard A LOT. Now she doesn't trust me anymore and idk if I'll even be allowed to see him. We've been dating for 9 months, we're both 18, and my mom doesn't want us to even hug in front of her. I feel like she'll never look at me the same ever again. What do I do...
