Spotting while pregnant

Li

so I'm 7 weeks and last night I started spotting (brown blood). I'm still spotting and I have lower back aches. I'm getting a little worried 😟. Anyone experienced this and it was all ok??

***Update***

spotting has stopped and saw my OBGYN. Ultrasound looks good and even saw the little heart beating. Hopefully it goes smooth from here and out.

thanks ladies for your advice.
