I need some reassurance please!

I’m 6 weeks and have been having cramps off an on throughout the pregnancy.

Yesterday I had my transvaginal ultrasound and saw the baby’s heartbeat though I wasn’t able to hear anything.

I’ve been feeling fine today other than the usual nausea and loss of appetite.

When I went to the bathroom I noticed a tannish-brown/possibly pink-tinged discharge when I wiped. I’m sorry for the gross photo!

Is this normal, and could it be from the ultrasound? Or should I be more worried?

This is my first pregnancy and all of the unknowns have made me incredibly anxious.

Ok
