Do you think there is a SLIGHT possiblity? (Asked earlier today w/o a good response!)?

Your possibility is 20-25%, as in any other month you're trying to conceive. Many of the other symptoms can be related to progesterone and its breakdown products, which everyone produces in abundance just after ovulation (I've got some of these symptoms myself just now, ovulated on the 13th.) HOWEVER, the spotting is definitely a hopeful sign! 30% of women get implantation spotting -- here's hoping you're one of them!! Lots of baby dust to you!
