call me crazy?

so, I just need to say this. I may be crazy. But here it goes. September 20th I got a period, I think. it was almost 2 weeks late. Only last 2 days. super light. But all month (my husband and I have been ttc) I haven't been feeling myself. I've been feeling...off. ive been dizzy at times. head aches. back pains. feeling like throwing up. crazy vivid dreams. I have also been more tired than normal. waking up late and taking a nap when I get home, which I normally don't do! what. does. that. mean? I keep going back to the fact that I am crazy (lol) because I don't want to get my hopes up!
