Could it really be happening?

So this month has been a busy one for us but we are still TTC though it has been our biggest struggle so far. This month I didnt get a positive opk but I didnt test very long so I think there was a chance I missed it. I havent been trying to pin point any symptoms on our 2WW because ive done this to myself so many times before and got negative results. I have about 4 days until my missed period and I woke up feeling extremely nauseous, to the point where I jumped out of bed ran to the toilet and my mouth was watery like a faucet. Then all of a sudden it just stops. I didnt actually vomit. That was the first time thats ever happened to me. What do you think? Possibly pregnancy symptom? Im not getting my hopes up but just never had anything like that happen before.
