Im 7 weeks pregnant

I had very bad nausea (no vomiting) and loss appetite during 6-10weeks. Nausea stops and appetite back to normal but i was vomiting everything that went into my stomach and also i had heartburn. Went to see gp to get my heartburn treated with meds. The vomiting gets better. And now im 15 weeks with no nausea.. only mild heartburn come and go and vomiting only if i eat too full.
