Finding out 👶🏼

Has anyone ever went for an ultrasound for something else and found out they were pregnant?🙃 I have an ultrasound tmrw to check on my ovaries/cysts and there's a slight chance I could be prego. I believe I mighta had IB a few days ago. I just keep thinking what if I go for the scan and find out.. would they be able to see anything that early?
