Chemical pregnancy lost on 1/20 and still no period

Katie
I had a full period on 1/20 and I still haven't started a period again... I've been testing, but no luck. I have a lot of egg white cm. I made an appt with my doctor in a couple of days, but has anyone experienced this?
I keep hoping I'm pregnant again, but no positive tests yet. I have PCOS, so that of course messes with things
