What's different ?

Jocelyn • I am 20 years old. I`m in college to become a Registered Nurse. I`m married to the love of my life Kyle.
Normally on my period I have no appetite what's so ever. And I have to force myself to eat a banana or protein bar so I can take pain medication, for cramps. However this cycle I'm craving and wanting to eat everything? Why the sudden change now? I've been having periods since I was thirteen and never ate this way with them. Is something wrong ? Could I be pregnant and still have a period ?
