Early Pregnancy Symptom: Discharge?

I'm 4-5 days from getting my period but i've been having strange symptoms. Yes, we had sex on the days before and on ovulation day plus the one after (and used preseed). My boobs are swollen and extremely sore, i am able to sleep from 1am to 2pm and still need sleep, headaches galore, one experience with heartburn (haven't had it since i was younger), cramping off and on but alot lighter compared to my normal pain by now, got sick a few times, and today (5 minutes ago) i had (sorry if tmi) milky white discharge, leak down my leg! (i only get clear before period, never had this). Opinions? Personal Experiences? i had cramping over a week ago which went away for a little. (possible implantation then). Ovulated between the 4th-5th.
