I am 47 years old I drink heavily every night but lately my breast have been sore and having hot flashes not sure if I can get pregnant or early signs of menopause?

Or alcohol poisoning so visit a doctor and find out for sure and stop speculating.

At 47 why would you be having unprotected sex? Thinking you are pregnant would indicate that thought on my part. Better get yourself to a doctor. Of course leaving the booze alone will help your thought process a lot.
