Need opinions:

So with a lot going on I haven’t been great with my pills this month. I’m on cycle day 20 & my expected period is in 6 days. I noticed yesterday and today my boobs hurt so bad & I have been feeling eh and not sleeping well. Today I to dinner & drinks, I had 1.5 drinks and I started to feel so sick. I drank water and had some appetizers but by time our entrees came (pretty quickly) I was in the bathroom throwing up.

Possible pregnancy? Or just PMS and a bad cocktail? Currently out of pregnancy tests so that’s fun lol
