6 weeks and symptoms stopped

Tierra • 👼🏼6/2018 🌈👶🏼due 8/13/19

I'm 6 weeks and 1 day, all of a sudden my symptoms stopped, my breast aren't sore anymore and I wasn't nauseous at all yesterday. But this morning I felt nauseous. I've been spotting off and on (very light and pink) since 4 weeks, I have no cramping but I feel like my period is coming most of the day but nothing happens.

Should I be concerned?
