Pregnant? am I going nuts?

I'm 24 years old, and I know the whole rundown with riding the crimson wave each month. I get the cramps, the moodiness, the whole nine yards.
But something feels different now.
Me and my boyfriend have been together for over 4 years and we have unprotected sex, but do the whole pull out method (I realize this isn't 100% effective)

My period is due in a few days now, but I've been feeling differently than my normal PMS. I've had very slight cramping in my lower abdomen for about a week now. On and off, I've been feeling a little queasy, but as quick as it comes on, within a min. it goes away. My boobs are a lot bigger and more sore than they are usually before I get my period. So sore I started wearing a 36 D sports bra with underwire and I'm still pouring out of it.
I don't know, I just feel weird. I feel this heaviness in my lower abdomen and I find myself a lot more quick to fly off the handle than my usual PMS.
I took a pregnancy test, which said negative, but I took it a week before my period is scheduled, so I'm thinking that it was probably too soon to test.
And I know this is probably irrelevant, but before I even thought I could possibly be pregnant, I kept having dreams of me and a baby boy.
Am I going nuts? Has anyone else gone through this?
I know just waiting to see if I miss my period or not is the best way to find out but I would like to have some kind of idea that way I could be extra careful at my job.
Any word back would be awesome.

there are a few tests that can tell "up to five days before your missed period" im not exactley sure which EPT that is but I know its that brand...you may want to try one of those
Its better to assume you are though then not because of the different changes you will have to make to your lifestyle (like being extra careful, and taking more vitamins) things that cant hurt to do anyway if youre not but can hurt if you are pregnant and not doing them

hope that helps a little

it can be stress too are you stressed? you can buy a ept test that can tell you sooner or go to the doctor

you're not crazy, but your hormones at this time are going crazy. they are to blame for the engorged, sore boobs, temper, and possibly the dreams. sometimes, every once in a while, I'll have a bad cycle where the soreness lasts all month, none of my bras fit me, and yes, I have dreamed about my children too. so if you're crazy, then so am I! lol.

you could def be preg, however. easy. (funmail me if you want).

you need to wait to take a preg test till a week after your missed period. the preg hormomes won't start appearing till then, and that's what the preg test has to be able to detect.

best of luck.
