Sickness at 38 weeks?

Roxanne • Pregnant with baby 5, due June :)
I just experienced 3 days of braxton hick contractions that where often regular but not very strong. Well they phased out over yesterday and today I feel great considering I'm 38 weeks pregnant although I've had very little appetite today and at 12pm realised I hadn't eaten at all today so had some lunch, I now can't stop being sick. I don't feel poorly just have sickness again. I have midwife this evening but I'm wondering if anyone else had experienced a return of sickness at the end? X
