I think my anxiety is giving me symptoms of pregnancy therefore giving me more anxiety

Y’all see how this circle goes right? Here’s the thing, I have been on birth control for two months, I take it every day at 10pm to the minute, my boyfriend has always worn condoms and always pulled out.

But I have horrible horrible anxiety that is making me somewhat nauseous (not really to the point of that metallic taste but it feels like my throat is closing up and my jaw is tense, so like not really nauseous but it’s weird) also I think I keep getting the super woman sense of smell that all pregnant woman seem to get whenever I get a strong whiff of something. (But then I realize that my family is smelling it too and it’s not constant it’s literally like a second then it’s gone) idk man.

I think I’m just being paranoid. So yeah, for the women here who have actually been pregnant, can you tell me what the symptoms actually are and what they are like so I know? And am I being paranoid or am I being smart?
