Spotting Every Day

I am 8 weeks 6 days pregnant with our first baby. I have been spotting every day since about 6.5 weeks. Mostly brown/ tan in color but sometimes bright red. I had an ultrasound at 8 weeks and all was great and the Dr said they couldn’t see a reason and sometimes it just happens. I feel like it’s a little worse every day and called my Dr shortly after the US to let her know it’s worse and more red in color. She is encouraging me to just try to stay calm, she said if it continues they may do another ultrasound to investigate further but ultimately it may just be my body and there isn’t anything to do besides try to relax and rest when I can. I’m just looking to see if this has happened to anyone else?
