what is happening!?!?!?

Amelia • Joy Rosemary McCarty 08/15/17😍👶🏼
I'm 7 weeks and 2 days pregnant and starting at about 5 weeks I was experiencing extreme nausea and about week 6 is when I started vomiting and now at week 7 it's gone down soooo much!!! I'm still nauseous and I still get dizzy, but I haven't thrown up in 4 days.  I can eat most of everything I want now. My boobs are still really sore and I'm still extremely exhausted but I'm scared that something could be wrong!? Could this be a missed miscarriage or a start of one?? Please comment and help me out!! This is my first pregnancy and it took us over 9 months to conceive!
