Super nauseous

So I had a positive OPK yesterday which is right on track for me since I usually ovulate CD 19-today. Usually I get some slight nausea that lets me know ovulation is close but this month it is extreme like so bad I can’t eat or drink and I’m dry heaving at smells. I didn’t ovulate last month due to stress but I was wondering if anyone else gets like this? My sense of smell is off the charts, I’m picking up the slightest smells as well
