I had a short peroid(4 days)Jan 18 through Jan 22' 06 (usually lasts longer)--and have been having 'some' unprotected sex -- and recently I stoped taking the 'pill'-- while having sex, a thick white odreless discharge emerged, very unusual...I took a pregnancy test -neg. Should I retest in a week? What's going on w/ my body? Could it be from stopping the 'pill'? Could I poss be prego?
