What Causes Excessive Vaginal Discharge With Spotting?

I'm 30 yr old 200lbs 5ft and was on implanon for 2 yrs with no periods. I got impanion out may 17 and 9 days later I was ovulating. Reason I think I know is very large increase in vaginal secretions like egg whites no smell. 4 days after ovulation I'm spotting once a day? Is this norml? Could I be preg or is my body out of wack. Maybe implantation bleeding? I spotted now for 3 days but only once a day and first time was a lot?
