Yes. Both migraine and nausea was and is normal for me. Week 16 now, no more nausea but still have migraine/headaches almost on a daily basis. I try to drink lots of water (without getting myself bloated) or drink lavender tea or put axe oil on my temples and back of my neck. It helps.
nausea is normal in pregnancy. some time you may have light headaches . But I am not sure about migraine
