What's going on inside my body?! Please let me know if this has happened to you.

My period is due today, but I don't have any cramps. I'm still having white cm, and my cervix is soft. I had cramps about 3 days before my period was due, they started more than a week before my period and lasted up until those 3 days before my period should arrive. I've still got tender breast. I do have my usual tiredness and increased appetite. I'm like clockwork, and don't even feel like I'm getting my period yet, could this be some weird period change? Has this sort of thing ever happened to anyone else, and what was the outcome? I've been ttc conceive for a few years, and doubt I'm pregnant. It just seems impossible. I haven't been pregnant before, that I know of. I know I should just wait it out, until AF arrives, but I don't have anyone to talk to about this, I'd just like to read the comments. Don't want to tell my fiancé, he will think I'm pregnant and I hate seeing the disappointed look on his face when I tell him I got my period. Makes me feel like a failure. So anyway, have any of you had months like this?
