VERY THICK l discharge?

Ive had unprotected w/ my bf of 4 years, planning engagement, if we get pregnant its okay. Last time we had unprotected ... he might not have pulled out in time. before the 'big bang' lol but just moments before so its very possible the little fishies got in there... lol. My period is due on july 4th. Just the past 2 days ive been having THICK THICK white discharge. I mean like peanut er thick... but no odor or color or itching. my period isnt due for 14 more days... is this an early sign of prgnancy?? If it were a yeast infection it would smell and/or itch and be chunky... any thoughts ??? ;/
