Ate a good amount of milk I didn’t realize was spoiled, 27 weeks pregnant

I had 2 bowls of oatmeal with milk that tasted kinda funny, but I thought it was the oatmeal since I had gotten a different brand. I like my oatmeal soupy, so I had quite a bit of it.

I go to pour my daughter a glass, and all these nasty chunks float up to the top of her cup and my boyfriend confirmed that the milk doesn’t smell good.

I’m 27 weeks pregnant, so I’m kinda freaking out! Is this something to call my doctor over?
