I tested 10dpo and it came out negative and I'm supposed to get my period tomorrow, but I always have super bad cramps that leave me stuck in bed and horrible back pains and my breasts always end up so tender and sensitive that I can't even wear a shirt that may be a little tight, always a week or two prior to AF showing up, but I'm not having anything that would make me think my period should be do any time soon. I have slight tenderness to my breasts and when I wipe theres like a barely noticeable light pink line, which isn't normal for me the day before, as I never spot or anything until I wake up with my period and I'm just wondering if it could actually be my period being off this time or something else
