Stress or morning sickness?

Sa

So I started having some brown bleeding Saturday afternoon, and since then had spotting. I've spoken with the nurse and said it's common, to just rest and no sex during this time.

My doctor said it's common as well even pregnancies that go to full term. He said he has ordered tests for hormone levels every other day till I reach 10,000 or if we see a trend in the wrong direction.

I've been anxious, worried and I'm pretty sure stressed. I've had symptom changes and now having more saliva, nausea, and diarrhea. Still have very light cramps, hunger and thirst.

So is this stress or morning sickness? I'm waiting for my test results. Hoping all positive.
