For a brief description of what my cycles have been through, here it is:

Jan 17th we had sex
Jan 19th I had a period
I was due for a next period Feb 15th, but nothing came
Feb 17th I had some cramping that lasted about an hour
My breasts started to get sore and tender and feel heavier
They hurt by my under arm area, and on top and bottom

I finally started my period 8 days after it was suppose to show... Im on day 2 of my period and my breasts are killing me! I did take a pregnancy test on Monday, feb 21st, 6 days after my period was suppose to show and it was negative.

Is this normal for your breasts to feel this way into a period?
In the past, Ive had soreness before a period, but once my period begins, it goes away.

Im just trying to figure out if this is normal? I see tons of information about getting sore tender breasts before your period comes and then having it go away after your period has begun. Im in my second day of this period and its getting worse, especially at night, when I have to take my bra off to put my pajamas on.
