what does this mean

I have one week before my period. I am having cramps. My cm is creamy and white. My cervix position is high and hard. My boobs  are sore around the nipple and I feel bloated. Last week 4-5 days past ovulation I was throwing up? Does this mean i have a chance of being pregnant?? I have been trying so hard to get pregnant. Just wondering if anyone experienced this in one of their pregnancy.... kinda afraid it's pms. I use to pms 2-4 days before my af. Just my anxiety is bothering me and trying to understand all this
