I am 3 days late for my period.

I am experiencing:

1) cramping for about 4-5 days now

2) sore enlarged breasts but, not until the day my period was originally due. I usually experience tender breast right after O until my period.

3) yesterday at The supermarket I broke out into a cold clammy sweat for no reason and felt dizzy.

4) increase in frequency of urination

I know a lot these could be PMS related but, the dizziness and clammy sweat I broke out into yesterday are making me feel different.

Any thoughts ???
