Hi expecting mamas!

Wondering if anyone experienced brown spotting at 13 weeks that was happening on and off for a day? I haven’t experienced any spotting during the first 12 weeks until now. I only see it when I wipe and it’s not enough to soak a pad but a little is seen on panty liner. I haven’t called the doctor yet as I wanted to watch it for a couple days but I’m starting to get a little concerned. Anybody experience this? What did you do? Did you call the doctor? Could this be a result of dehydration? Any suggestions/help is appreciated!!!
