Please Help me, no PMS symptoms?

I wrote quite a long question earlier, no answers for two hours now, so it must be too confusing, I seriously need someone's opinion who is a mom, or pregnant...I'll try to simplify my question. I am trying to get pregnant, and am about one week from my period. I have no PMS symptoms, which I should, no sore , just dark areolas, feel weak, sick, and very flushed, also wierd cramps that I only get while in the middle of my period, but, no period? I also have to pee constantly, and know we did it at exactly the right time, HPT shows a negative, but, I know from past pregnancies, it won't show up for about another 2 weeks if I am, and not to be gross, but i'm 35, and feel very wet and squishy down there. Could this be early pregnancy-no PMS symptoms?
