Milky CM & some what sore breasts HELP!!!

Hey ladies so I'm TTC for baby #1 I'm in cycle day 16 (apparently my second most fertile day) upon checking my CM today I noticed it was milky (white/watery) like. Yesterday it was watery. And along with today's CM result I had slight tender breasts. My AF is not due till 10/10/15. Is it possible that I can be pregnant? I've BD on days that I haven't been (as per glow) so fertile and on my most fertile day as well. Please help... Don't just view anyone with some what of an answer is highly appreciated BABY DUST TO ALL!!
