Anxiety about sex after vasectomy

My partner got a vasectomy in early Nov. he has been cleared 1 time. We have had sex with a condom and pull out method, till he can get his second test sample done. Is it weird I still have anxiety around my fertile time that I could get pregnant with a vasectomy, condom and pull out…? I feel stupid but my anxiety just fills me with the thoughts that I could be pregnant..

Not looking for rude or negative comments. Or to be told I shouldn’t have sex… just because something causes some anxiety doesn’t mean you don’t do it.

Performing on a stage causes anxiety but you still do it.
