pregnant??!

ok so I was suppose to start my period the 14th of this month..it is now the 22nd and no period in sight. last week tho I did have one day of a slight period, cramping and spotting mostly brown with some pink, I did have sex with my husband maybe a week before that with a condom but he wasn't fully erect so some might have leaked out sounds bizarre I know but I've talked with a dr and read online it is quite possible. anywho since then I've experienced severe mood swings, head aches, my nipples are sore and I've also have had a lot discharge. it's gummy, milky white, no smell doesn't itch nor sting or burn, there's always a lot. I'll up load a pic. sorry for the pic but idk what it is. I took an ovilation test and pregnancy test today and both are negative. I don't have any stds either. can anyone help me out?!?!
