I am currently sick, period was due 2 days ago, possibly pregnant? But all tests say Negative?

My husband and I just got married in October this year. Since we got married we haven't been trying and also not preventing from trying to get pregnant. The first month after our marriage, I did not get pregnant and got my period. This cycle he and I have been a lot less cautious, and basically have said oh well. He has only pulled out once. My cycle is very average, about 28 day between each period, and it usually comes on time. I am currently sick with a winter cold, my phone altered me that I was supposed to start on the 9th. it's now the 12th and nothing, not even cramping. He did inseminate on my highest risk for pregnancy day, November 28 (35%). We usually have sex at least 3 times a week, and he usually doesn't pull out now that we are married. I have taken 3 pregnancy tests, 5 days before missed period, on the day, it was supposed to start, and last night. All have said negative. Is this possibly a sign I am pregnant? or is it more likely that my pattern is off because I am sick? oh I only got sick Yesterday too.
