Hey everybody. Today is the 21st and there is (in caps) still no sign of myy period! So far there are no signs of pregnancy except for extreeme fatigue and this pain in my lower left back that shoots down my leg only when I walk. I dont know whether to think im pregnant or what. My cycle is very dependable and it hasnt showed up at all. No spotting, no nothing!! I have gained a few pounds (maybe 3-5). It seems like no matter how many hours of sleep I get, it isnt enough. I get the full 8 hours need at night. Then when I get home at noon, I have to take a 4 hour long nap. Then I get right back to bed at 10. Please somebody help me to understand whats going on. My breasts dont hurt, but my nipples do. Should I not even wait until october (for my next period to come) to go to the doctor?? I am far past due for my cycle. Usually I get my period at the end of the month(maybe the 30th or 31st) or the beginning og the month(the latest was the second). That has been every month since I got my period. Now it is the 20th of september and my last period was aug. 2nd through the 5th. (i dont know why it was soo short) please some one give me any advice or suggestions of what you think I could/should do!
