I think maybe I can't tell the difference between watery CM and EWCM. I'm thinking that the big globs in my undies were watery CM. I guess I will find out when I get af and count back 14 days to see which part of my cycle I ovulated in. I also ended up getting sore nipples for 2 days which I generally associate with ovulation. When we actually start TTC I am going to invest in quite a few OPKs!!
