Help! Tell me not to overreact.

I went 💩 this AM and shortly after I noticed I had light pink discharge. I took a bath and it seemed to be disappearing. Called my OB, who said not to worry that this is common. I was able to pick up the heartbeat on my Doppler. I just went to the bathroom again and now it’s light brown. I’m hoping it’s just residue from an old period, but doesn’t make me feel comfortable either way!

No cramping, and no pregnancy problems thus far. The only thing I can think of is making the tension from 💩 or a cyst may have ruptured... I have PCOS.

Anyone else? I go Wednesday for an appointment.
