About 2 months w/o AF

So I have been testing and still BFN. I HAD MY PERIOD 6/15 and still nothing. It's driving me crazy!!! I have been feeling nausea, craving, emotional and throw up when I eat any kind of meat. I don't like to eat the food that I always eat and my nipple are light but huge than before. I feel bloated all the time and I do not understand what's going on. My period has always been on time. Help anyone!!!
