pregnant? should i test?

jasmin

my period was due yesterday & for the last 2 1/2 weeks my breasts have been sooo sore and achy, more full and firm & my nipples are bigger , oh and i have noticeable blue veins that i've never had before on my boobs.. i've been cramping a little bit, & tonight when me and my boyfriend had intercourse afterwards i was in such bad pain, i had the worst cramps made me feel nauseous & just want to cry..
