Stomach bug or morning sickness?

Alicia

I got a peak on cd day 16 so thinking I ovulated ethier cd 17 or 18. Got the stomach bug on cd 22 felt terrible for 2 days and then was fine. Have been eating normally no problems other than indigestion. Until today cd 25 and I have nausea and throwing up again. But I’m constipated now. I’m confused. Is this the stomach bug showing it’s ugly face again. Or maybe morning sickness??
