Panicked.... please responded

Hello all, I’m currently 13 1/2 weeks pregnant with my rainbow baby and today when I went to the bathroom when I wiped I noticed some light brown spotting in which it’s kind of been going on now for a couple hours. It’s only there when I wipe and it’s never been a red or a company with heavy cramping I was just wondering is this normal or did this happen to anyone else. I did call my doctor and they said there’s nothing to worry about since it’s old blood but this baby just means a lot to me and my husband. Thank you so much in advance.

UPDATE!!

At work last night I was telling some of the doctors I work with and they immediately did in ultrasound and the baby was very very active spinning around like crazy in a good heartbeat the spotting has since laid up for the last 12 hours thank you so much everyone for responding you made me feel so much better!
