In very early pregnancy?

I believe I may be pregnant but not sure....I'm not asking if I am or not because I know the best way to find out is thru a test but if I am it may be to early and I just want to hear opinions. I started my last period on Jan.6 and had unprotected on that day and on the 7th,10th,12th,14,15,and 16th. According to a ovulation calender I ovulatuon is the 15-21 but I believe I may have ovulated early because right after my period around the 12th when I had I noticed I was really really wet and my *** would be white and around the 14th it turned clear and was a lot of it and on Sunday Morning at 1 am I went to used the bathroom n noticed brown stain in my underwear and pink spotting when I wiped and that was it it went away. And then a hr later I was craving some icecream n doritos and I actually ate them together and I never even done that b4 and Monday I wad feeling nauseous and continiously hungry and my bd is feeling sick too n he never feels nauseous and today my gums are sore and bleeding....what do you think? Plz help!
