Everyone is saying I’m pregnant

So I work at a daycare and about a few weeks ago I was telling all the kids they smelled good (cause they did) and my coworker was like omggg are you pregnant? I was like no lol, then I hung out with another coworker of mine and we went to a Mexican restaurant 10 minutes after we left I threw up and she was like yup you’re pregnant (I thought it was motion sickness from the car). Now almost a month later all the kids in my class (13-20 months old) are suppperrrr clingy to me and every time I step out of the room they freak out. So another coworker of mine keeps telling me I’m pregnant. Y’all I’m starting to worry. I’m starting to get migraines and I just feel off. I’ve known for a few weeks now I need to just buy a damn test but I was just curious if any of you ladies had any similar experiences.
