I am 8 dpo and for the past few days my breasts have been sore when I take my bra off. Its only my breast area not the nipple. They feel very heavy when my bra comes off. I have also been extremely tired. Almost like I can't wake myself up... My period is due the 26th but I am hoping to have a positive test before then. I have used a couple dollar tree preg tests and they came up negative. Does anyone have any experience with these tests? I hope I am pregnant... fingers crossed and many prayers are much appreciated!
