Light spotting

TMI!!

I’ve had pink, then red, then brownish pink spotting for the past week (I’m 7 weeks pregnant now).

It’s only when I wipe and it’s only been once a day- i.e. the spotting has happened three times, once on different days.

Is this cause to be worried? At my first appointment my nurse said if it filled a pad for an hour for two hours I need to be worried. But I’m a FTM and freaking out 😅

Thanks!
