Almost 3 months and nausea

I tried searching, but couldn't figure out the right words to get an answer. I'm almost 3 months out and have had absolutely no issues until this past week. It seems like everything/everytime I eat I'm having much more nausea than I've ever had (really none up to this point). One morning I ate cottage cheese, just like I do almost every day, and immediately threw up. Several times since, I'm getting really gurgly stomach, sweating, and feeling sick to my stomach. This has been going on for about a week. There's no "pain", just nausea. It's making me extremely uninterested in eating or drinking anything.

It's just so strange, up to this point, I've really had such a stellar experience, I'm concerned.

Thanks for any insight and/or advice.
