When and how did morning sickness begin for you?

I’m currently 5 weeks + 1. I noticed last night that I started feeling nauseous after dinner. Not bad, and no vomiting, just a little queasy. Today, I had the same thing with breakfast. As soon as I finished, I felt nauseous, and the nausea has been on and off all day since this morning. The nausea is a little worse today than it was last night, but it still not bad. I’m just wondering when and how morning sickness started for you. Was it around 5-6 weeks, or later? Did it start suddenly, or was it more of a gradual thing? Up until now, the only symptom I’ve had is sore boobs!
