I am 22 years old and I have just been extremely emotinal these past two weeks, and just everything either makes me mad or I just take it to heart. And for the past two days I have had really bad nausea, especially in the morning. I have never had any problems with being so emotional only a few days before my period is when I get emotional. I am pretty sure I am not pregnant I got off my period a week ago and me and my boyfriend did have sex the day before my high fertility days started. Is this normal, because this is very new for me
