Morning sickness - constant or eases?

Hi everyone, I'm about 6.5 weeks pregnant and slightly worried. For the past few weeks I've been feeling nauseaus thoughout the day and night, with sore nipples and feeling tired. Today however all these symptoms seemed to have eased. I've had cramps on my right which I got checked out by the doc today and she said it's muscular and when feeling my abdomen said everything his fine. I guess my question is, has anyone else experienced in their pregnancies symptoms which ease at 6 weeks and gone on to have happy babies? I'm in the UK and the midwife won't see me until i'm 8 weeks and won't do a scan until I'm 12 weeks along, it's frustrating! xx
