I think I'm pregnant!!!!

I been having a white discharge with no smell for about 8 days my period was due on the 25th still hasn't come but my labia is swollen and very tender not painful really but sometimes it gets hard other times and with heat applied it gets soft I been having sex with only my fiancé he's ejaculated in me all month! 
What could this be? Is it uncommon to have vericose veins this early in a pregnancy
