Spotting cd 9

Linky

This is our second cycle of ttc. I had a paragard in for 10 years. First period after I removed the paragard was normal, this one I had one wipe of red blood then nothing for a day. Next day I had spotting for two days and then af arrived full blast. I usually bleed for 6/7 days, this time I only bled for 3 days then some spotting. Now 3 days after my period ended I had blood mixed into my egg white cm. What is going on?
