Husband depressed????

Paulina
So I was wondering if anyone had the same situation like me... When I was pregnant with our son my husband was acting really depressed he wanted to sleep all day, he was on sweatpants or pjs, he looked like a mess:( not showering everyday (like he ususally does) he was getting late to work, he also was very irritable and even lost a bunch of weight and after my son was born he was fine. Is this something that is normal on men!? Im just wondering cause we are trying to concive for the second time and I'm worry this might happen again.
