Well I just looked back through my old threads from last season and it looks like she began the first stages of glowing (getting a shade or two lighter) a month before ovulation. Now at that time I didn't know how to properly palpate and had no clue as to her follicle size but so far this season, I have been able to palpate with success. 4-5 follicles about as big as one of those large marbles. She's a shade or two lighter so I guess I will start looking out for "the glow" and eventually an ovulation very soon. Actually she's almost on schedule from last season. She began getting lighter in early January and was glowing by early February. She ovulated in late February and had her prelay shed in early March. (for the longest time I've been thinking it was Feb 23rd, but no, it was March 2nd. Haha. Dumb me)

Thanks for all the replies, everyone!
