Throwing up

So, was at lunch today with my mom, I got up to order a dessert, and then (literally 2 minutes to it) I almost threw up my lunch! It was a normal lunch I’ve had this week already. So it wasn’t anything out of the norm. Could it have been pregnancy?? I have a 6 month old, I don’t mind being pregnant, I wanted to breastfeed until 1 though! It would make sense, but the test I took last week was negative.

Oh and I EBF so I have not had a period yet.
