PLEASE HELP. 7 DPO...

Kalee
I was in Alaska visiting my fiancé from 03/12/16-03/21/16. I was most fertile the 14th-20th and ovulated the 19th. I had unprotected sex every single day of this week. I am now 7-8 DPO and I am having a lot of weird body changes. About 5 DPO I had pink spotting along with a lot of white discharge. The spotting lasted a few hours with cramping and the white discharge hasn't stopped. My boobs hurt really bad and feel very heavy, the veins are also very visible. I am very emotional/irritable. I feel SO bloated. I actually lost weight but I feel so heavy. Please help me understand what is going on, could these be pregnancy symptoms?
