I drank bad milk, am I going to throw up?

Hi! I drank about a cup full of milk. After drinking I noticed it tasted bad. Texture was normal but it tasted kinda... Off? I looked at the back and noticed it was over 2 weeks old!!!

I have emetophobia meaning I am afraid of vomiting. It's now been 2 hours and I feel fine. But I'm afraid of going to sleep because vomiting always comes during the night!

Am I going throw up? 😰
