Is 2-3 weeks too early for morning sickness? I’ve had to call in to work 3 times in the last week cause I’ve been dizzy and nauseous. Two days straight plus intermittently before and after. I never had symptoms this early with my first so I don’t want to get my hopes up. However my neighbour said she was violently throwing up by 2 weeks. My period isn’t due for another week but I have really irregular cycles. The average is 36 days but they could be anywhere between 28 and 40 days
