Sore nipples, a sign of pregnancy or period?

hey,i have been trying to conceive and lately i have had really sensitive nipples for about a week now and am not due for my period for another 5 days. i initially thot it was a sign of ovulation as it started about my ovulation but now im wondering if its an early sign of my period approaching??? could it be pregnancy sign which i believe is too early to know???

Its really a sign of both...Ive been trying the same as you and have had sore breast for a week, then I started my period...Its just really hard to say and the only way to know is to take a pregnancy test about a day before your period is to start...Hope this helps......
