Ovulation a day after period?

Sorry in advance for TMI. I have had intercourse almost every day since 01/14..got my period on 01/19..lasted 5 days,and I noticed the same day my period ended I had what looked like your typical egg white fertile CM.Had intercourse twice that day and elevated my hips during intercourse.we are ttc and i was just curious if this has happened to any of you..on my chart it states im not supposed to ovulate till 02/02 yet my CM shows me different.i have conceived in the past a day a after my period which resulted in MC.is it possible to have conceived before my scheduled ovulation date? baby dust to all =)
