Was heartburn and sore nipples a early pregnancy symptom for you?

I have irregular periods. I haven’t taken a test yet, bc of having irregular periods, I do my best not to hype myself up bc it has happened frequently where I THOUGHT I could be pregnant and wasn’t. However, I’m experiencing heartburn to the point of being nauseated and nipples hurt tremendously. Was wondering if this may have been anyone else’s first trimester symptoms

My SO and I have been having A LOT of unprotected sex. Not even using the pullout method. I’d be happy if we’re pregnant, but again, don’t wanna hype myself up.
