Exercise help morning sickness?

Miranda • I have a gorgeous three year old girl.

I had a bad morning yesterday - headache, nausea, didn’t want to get off the couch. But we went for a walk and I felt better, so I went out for the afternoon to my parents.

We took my daughter for another walk and when I got home I didn’t feel sick at all.

The nausea has only just started to come back tonight!

For over 24 hours I actually felt quite good. Is this a coincidence or does a walk help anyone else?
