Vanishing morning sickness?

I had extreme morning sickness with vomiting from 4 weeks until 5 weeks + 3 days.  Then it stopped completely and I got my appetite back.  I've had no cramping and only a tiny bit of light brown spotting now and then, but midwife says that can be normal.  I did get my HCG levels checked and they were 5023 on Thursday (5w3d).  I'm having another draw this morning to compare. I still have other symptoms such as sore breasts and bloating, but has anyone else experienced morning sickening that disappeared in early pregnancy?
