Advice for the partners?

Olivia
I'm 17 weeks pregnant and haven't experienced any emotional spells yet, until now. I absolutely lost my marbles when my partner came home from a very long grocery shop only to discover he didn't buy anything substantial for lunch, and by this time I am so hungry that I almost feel sick. I know I'll get emotional but I just lost it. I feel bad towards my partner because I know he tries but I want him to try and understand how I'm feeling and not question me for being emotional like he did. Has anyone's partners done research that you could recommend? I want him to read about the changes I'm going through to understand how hard pregnancy really is for us women.
