Has anyone else had in explained nausea for long periods of time

So I have been having really bad nausea since June with no explanation. I'm not pregnant, no ulcers, not gas and not acid reflux there is literally no explanation. So after going to my doctor a couple times a month since June he finally sent out a referral on the 6th for them to contact me and its been 2 weeks and they still haven't called. On the 7 - 8 i had some weird spotting never have spotted before so I thought it was weird (I'm on birth control and sometimes have unprotected sex with the person im seeing) and still getting nausea. Then went on the 13th to have my wisdom tooth and a cracked tooth removed (the pressure from the wisdom tooth broke it right in the middle.) So after that for a few days it felt great no nausea or anything so I thought it was just the pressure from the teeth that was throwing my body off. But boy was I wrong a couple of days ago it came back full force along with diarrhea in the middle of the night and made me jump outta my sleep. I have never had motion sickness before but driving in the car made me wanna puke I have no clue what's going on with my body and its starting to get really annoyed with the constant nausea. Sorry just needed to vent
