Please help me!!

Holly • Got my BFP on the 8.7.14 xx
Today I woke up experienced very watery discharge and a lot off it, and when I wiped there was a very thick consistency type discharge that was light brown. I'm 12dpo this morning and very confused as I had a smiley opk on the 29th June and last smiley on the 30th June and ovulated on the 1st July ? Please help me I'm so confused...
