What Are The Chances Of Pregnancy?

I had my period on Oct 1st that lasted the usual 5 days, with the 2nd and 3rd day being very heavy as usual. On the weekends of Oct 22nd and 29th my husband and I had unprotected sex, although he did not ejaculate inside of me and we put on a condom all three times in the end. Nov 1st I got my period as expected however it only lasted for 3 days and was very light. This is the shortest and lightest my period has been in about a year. I have not changed my diet, had not gained or lost any weight and did not change anything about my daily activities. I was still having mild PMS after my period had ended so I took a pregnancy test on Nov 4th. It was negative. Since this time I have been unusually fatigued and bloated. Also in the last 3-4 days I have had a milky white, sticky discharge that does not have a smell and my breasts have felt slightly heavier than normal. I have also gained 2 lbs in the last two weeks, which I am typically very consistent in my weight. I was just wondering what the chances of pregnancy could be at this point and if I should take another pregancy test or wait for my next period to come?
