Help!!!

I have been ttc for about 4 years now. And i have had all kinds of symptoms that made me believe that it was my time for a baby yet i always get a big disappointment. Yesterday i was really sluggish while at work. I had a bloated feeling with a pain that was very irritating right on the side of my belly button but a little below it. Not only did i have this pain i had out of the blue pains that kept attacking my lower abdomen. Sharp pains that only last a few seconds in my breast and a backache. The backache didnt really hold my attention because im on my feet all day so some days my back tends to hurt. Ive been really wet down there and have had thick white discharge in my underwear. My period should be here in 7 or 8 days. Im always around 26-29 days. So my questions is do anyone think that this could be just pms or should i continue to have hope.
