spotting at 7 weeks but no cramps

Deena
I just started spotting red I'm 7 weeks but no cramps or clots.. it's also not getting heavier.. should I worry ?
UPDATE-- I ended up going to the ER just because I knew I won't sleep tonight with all the stress. I just got out of the ultrasound and they saw my little bean and a heartbeat of 126 bpm.. no clue where the blood is coming from still waiting to see the doctor.
