I had a similar experience before. My morning sickness was quite bad until week 8/9 when I don’t feel much. My breast pain reduced the moment I found out I’m expecting. I was very worried but same, my gynae check wasn’t due yet. But the morning sickness came back and worsen the following week. If you’re really worry maybe you can call in the clinic/hospital to ask for advise since you’ve an episode of miscarriage before.
