I am going crazy!

This is my very first cycle that I am TTC. My "fertile" days were April 6-12 and I am pretty positive I ovulated on the 10th (no OPKs). I had unprotected sex every day from the 4th-10th, at least once, most of the time twice a day. Usually after my fertile week is up, I don't have any CM. The past two days, midday, I have had a gush of very warm, white, lotiony-textured CM. I have also been cramping a little and had headaches and a lot of gas! This is different from any cycle I have had and I am always the same every month.  Have any of you ladies experienced something similar? This TWW is killing me and I'm barely in! I know that this is my first cycle but I want a baby so desperately and I just have a gut feeling I won't get pregnant! Am I a complete idiot for beginning to lose hope in my first cycle!?
