Week 7 and getting over my nausea ???

Okay, so I did start taking unisom and b6 because my first pregnancy was just so hard. I just started taking both at the first sight of nausea. After 2 weeks of vomiting on and off and nausea/food aversion, I feel fine! (I mean “fine”) like how I did around 12/13 weeks.

Here is my theory, my hcg levels were sky high! Like 6,000 at barely 5 weeks. Is it possibly they reached their peak sooner ??? They say the top out around week 9 but because I was relatively ahead could than mean I reached the peak sooner ?

Nervous because I had an ectopic a few months ago.
