URGENT!!! Spotting

I have very irregular periods, meaning I've never had one on my own. I had a laporoscopy and Hysteroscopy done in November to hopefully find my infertility problems so we could fix them. I have PCOS as well. So on January 4-7 I had a slight "period" just a lot of spotting and one day of constant flow. Well all of a sudden, I have been having slightly pink discharge and it has the consistency of an egg white or mucous. I was just wonder if anyone else has gone through that and could tell me why that might be happening!! Thank you
