PMS symptoms or early pregnancy symptoms

Marisa
So, around 10:30 pm i've noticed that two of my veins on my boobs are super visible when i didn't see them at all earlier today and i never see them. 
Today certain foods that i literally would eat multiple times in a week taste a tad bit odd and I have being expierencing cramps in the middle of my uterus on and off since i've ovulated just about 2 ish weeks ago. I don't get my period until 3/14 and i don't want to test too early. I rather wait until the day of my period to test. 
Before i test i would like some insight from you all about my symptoms and your opinions on what you might think is going on with me currently.
