anxiety for pregnancy

hi i’m a 17 year old with severe general anxiety disorder and i’m having some anxiety over pregnancy. i just need some education or reassurance that i’m not pregnant from you lovely educated women 😌

the last time i had sex was around one and a half months ago, we used protection as well as pulled out every time he finished. i got my period afterward but now my period is late by three days. do you think i may br pregnant.

i understand that what i’m saying may sound stupid or irrational to some of you but this is the kind of thing anxiety disorders accompany. and i’m not sure if i’m rationally thinking

or irrationally.

so yeah is it likely that i’m pregnant?
