Hi Jazb!
We don't answer questions around pregnancy fears unless the person has indicated that they are actually pregnant. It sounds like what you're experiencing might be closer anxiety.
This often matches up with having worries or guilt for having sex, or feelings associated with especially stressful periods of our lives spilling over into how we think about our sexuality. There's a lot of that now with coronavirus.
Are there wider things going on for you at the moment, or anything going on in your relationships that could be causing anxiety of this sort?
As you haven't had a pregnancy risk (intercourse without a condom, obviously broken condom), a missed period or taken a positive pregnancy test it wouldn't be helpful for us to talk about pregnancy symptoms.
This advice column could be really helpful though:
Why can't I stop being so scared of pregnancy?

Don't see why they call it lonesome.
I'm never lonesome when I go there." Connie Converse - Talkin' Like You
