6Weeks 2Days brown spotting for last 4 days

Be
I'm starting to feel so anxious. I have a sonogram scheduled tomorrow and I'm terrified of finding out that something is wrong. On Sunday I had a very light pink discharge when I wiped and since then anytime I wipe its brown with a tad bit of pink from time to time. What scares me most is that I just don't have any symptoms. No sore breasts, no nausea. Just bloating thats actually gotten a little better. The doctor told me that spotting is not normal. I'm feeling sad that as much as this unplanned pregnancy has brought me so much stress, I still want this baby very much. Trying to be accepting and calm. I know what will be will be.
