Anyone know why?

So ladies I’m not sure if I post here about this but random question... so today I had less then a bottle of wine (celebrations🙈) and after finishing it I stopped drinking because I felt drunk 😑🤪 all the sudden, I laid down and fell asleep and when waking up a few hours ago I’ve felt so sick and keep feeling like I’m going to be sick, got pains in my stomach, watery mouth and even drinking water I still feel so sick. Could this be a sign of pregnancy or am I being stupid and just hungover 😂 only because normally I can drink and drink and be fine 🙈
