Crazy feelings

I have been trying to get pregnant for over a year now. I have put on some weight so this cycle I decided to stop trying and go on a diet. I have only been with my partner 3 times this cycle. Now I am feeling tired and my boobs hurt. I have cut back on my soda consumption from 3-4 bottles a day to 1 a day. My heartburn has kicked up so much that I have to take my medication 2 times a day instead of only once. My next cycle is in 5 days. Crazy feelings.
