feel weird... first time

Cherry
Will you have strange craving for food you don't like, feel hungry every 2-3 hours, will feel the heartburn if you dont eat when u are hungry, feel nausea at the smell of cheese powder and can't stand the taste of salmon fish, porridge and etc... (by right I like it a lot) with a delayed period of 3 days? BTT temp has been consistently at 97-98 Fahrenheit for the whole week even before period due date... 
Before tat, I have some mucus discharge similar to the color of raw egg white after trying for tat on the same day for a period of two days and also some Light brown blood discharge right after sex yesterday for few hours...
