Hi,
I was wondering if someone could help me. My period is three weeks late, I have done a preg test, and that's negative. I have had all the signs for getting my period, cramps, bloating, lower back pain, sore boobs, but they just haven't come yet. I am a bit nervous and I am not sure what is wrong, this is the first time this has happened, usually they are like clock work. I am not overly stressed, so I am not sure what it could be.

Thanks for your help.
