Spotting in pregnancy

Sstar

I have two questions. I am 9.4 weeks pregnant.

1. I had light pink thin discharge yesterday and my doctor wasn’t ready to diagnose it further. She said it is pretty common. And also mentioned they will only investigate if I am soaking pads.

2. I often see brownish stain on my panty. Could this be because of excessive discharge? Or pee leak?

Any experience of pregnant ladies will help! I am too anxious.
