Depressed and anxious 24/7

A few months ago I had a few pregnancy scares and I grew very suicidal and depressed from it and I stopped having sex since then. I’m 16 btw. And I haven’t had sex since November and I’m on the combo pill but whenever I do something sexual with my partner (not sex) I still have that stigma in my head telling me “you’re pregnant”. I’m seeing a therapist in a few weeks to talk to her about this. Has anyone else had this happen to them?
