Confused

My period usually begins at the beginning of the month. Before that time, I have cramps, my boobs are sore, my face breaks out, etc...your typical period woes. This period (for March) I was expecting to begin between the 1st and 3rd due to the fact that Feb. only has 28 days and my cycle is 30 days.
My issue is I have yet to experience any cramping, my chest is larger but no soreness. I got a little worried and bought a box of ClearBlue home pregnancy tests, and tested myself each day consistently up today, all (5 out of 5) negative. Also my mucus is said to be infertile because its thicker, paste like, and on the white/cloggy side...

Granted I have been under a lot of stress i.e. moving into a new house, starting a new job, and being away from my family makes me a little home sick. I heard all this issues can delay a period but I didn't know if a change such as not experiencing the cramping and chest soreness is usual.
I have been with my boyfriend for almost nine months and we practiced safe sex methods...should I be worried or just kind of "go with the flow" (pardon the pun)...

Thank for your feedback.

Hi!
Booo!  ( for the pun ).  All of the things that you mentioned can combine to cause enough stress to cause your ovaries to fail to ovulate..  When you don't ovulate, you don't produce progesterone, and it is progesterone that typically causes all of the PMS symptoms.   Also, if you don't ovulate, your period will probably be delayed, sometimes for a few weeks, and may be extra light or heavy when it does come.
The Clear Blue tests are pretty reliable.  I would suggest re-testing in a week or so if you haven't had your period yet.
Good luck!
