Tell me about your signs of preeclampsia...

Okay, so I don't know what is wrong with me. I'm 33 + 3 with my third and I suddenly feel like I was hit by a truck. Out of nowhere I'm nauseated, I had to take my wedding rings off because they were cutting off the circulation to my finger and now the new rings my hubby got me (2 sizes bigger) are snug), I don't see any other signs of swelling, I just woke up out of nowhere with a splitting headache, and I just feel like something is wrong...idk how to explain it but I'm anxious and I have this sense of anxiety that I cannot explain. At my last appointment my blood pressure was fine and I only had "trace protein" in my urine but I just feel off. So...my question is, what were your symptoms and did they come on suddenly? Were there any initial symptoms before it hit ?
