I don't have much of an appetite once I found out I was pregnant. Not sure if its because im more in depth to whether or not I'm truly hungry or not because I need to eat better now that I'm pregnant or just because I am pregnant...if that makes sense?

I have occasional nausea nothing overwhelming, I have not vomited yet. I'm 4 weeks 5 days. When im.not nauseated but hungry I'll get something to eat. I'm craving chips and salsa cause I love some spice. Had a few bites and not I'm I'm really queasy. Is this a natural thing or am I being irrational?

Also, when does the intense nausea kick in? This is my rainbow baby so I'm a completely noob mommy. Haha

Thanks!
