Pregnant with occasional brown discharge

So I just found out I was pregnant on Thursday. And last night when I wiped there was a little light brownish discharge. I put on a panty liner before bed. Nothing on it when I woke. And no more for the first half of today. Around 2pm I peed again and when I wiped there was little more. I'm freaking out. I dont know how far along I am as I have PCOS and my periods are all crazy and my cycles can be 40 plus days long. I'm not in any pain.

Here are my test from the past 4 days

And her is the discharge. It's not very much and has seemed to stop for now
