Is it too early to have these symptoms.?

My husband and I tried to conceive last weekend. He is in the Marines and got to come home last weekend. The days we tried were the 21-24 and those were my cycle days 10-13. Lately I have had been cramping not really bad but still cramping. I have gotten light headed when I stand up head aches throughtout the day. My are really itchy and my breats are fuller and sensitive to the touch and it gets worse everyday. I have been waking up in the middle of the night having to pee. and it's like my baddle was completely full and I do that before I go to bed in the middle of the night and as soon as I wake up. I am starting to get really bad acne and I have never had really had ance maybe a black head once and a while but not bad ance. And I also so just the gut feeling. My husband also says he has the gut feeling too. I know it's too early to test. But it is too early to be having these symptoms? Or do you think my mind is playing trix on me? What do you think?
