Help - 11+5 - spotting

I woke up to light pink spotting in my sleep last night, and brown spotting this morning. I called my doctor and she said not to worry unless it increases. No cramping or anything. But my vagina has this weird throbbing feeling.

I’m so worried I almost fainted last night.

Has anyone has spotting this close to second trimester and things turned out okay? What could it be?
