Lower abdominal pain

Last night I had sex with my boyfriend and by the end of it I started feeling a lot of pain in my lower abdomen. After that I couldn’t even stand up straight or even go to sleep because of how strong the pain was. It’s been 24 hours since then and the pain has gone down but it’s still there. I can’t walk, lift anything or even laugh without it hurting. What should I do? Has anyone else experienced this? I don’t really want to go to a hospital because I don’t want to risk getting COVID-19.
