Help!! 😢

Today I had a good amount of brown spotting today. Had a pelvic exam and an ultrasound, saw a flicker of a heart beat, the dr. Says the baby is in a good spot, we saw more than he expected. and now the spotting when from brown to pink and rose color there was even a thin red clot. Should I be worried?? 😢😢 I saw my baby’s heartbeat today… And now it seems that I have some bleeding. I’m devastated and so worried. I would love to hear from someone that has experience the same thing. Thank you
