Hopefully I am Preggo This Month?

Hi ladies, I just need a little advice. It's about 4 days until my expected af. Maybe a little later because last month it was 4 weeks late. I think I ovulated around august 5th-10th because I had some clear gooey cm come out; and I don't usually ovulate because I usually don't have any cm ..that was a big sign for me..anyway I did the bd every day like I usually do, so the timing was perfect and everything. Now, I have been cramping for about a week and a half already, which never happens so early before my af comes. Also, right after I ovulated, my cm dried up for a couple of days, and then it came back (which is very unusual for me) and it was creamy, up until today, I had a lot of creamy cm. I've had some body aches, and a couple of headaches..and pretty moody. I also had lost my appetite for about a week (everytime I tried to eat I felt soo sick), until yesterday I got it back and was eating non-stop. Haven't been more tired than usual, and not much pains though. Could I be preggo maybe?
