Drank possibly bad milk?

Well.. we bought milk last night and it didn’t expire until the 27th. I had a glass this morning and thought it was a little odd (not sour). We wash dishes by hand and it honestly just seemed like I washed a dinner plate and then a cup. That was around 9-10am. I just went for another glass (9pm now) and it was bad again. I had my SO smell it and he said it smelt weird too. Mt question is, will I be okay? Will I be sick? Ive felt fine for the last 12 hours. I’ve been nauseas but I figured it was due to lack of sleep (27 weeks pregnant).
