Postpartum depression?

I gave birth to my first baby In January 2019 and then in April 2019 I found out I was pregnant again and I was only 3 months pp so I didn’t really have any type of depression at that time, so I have my second baby in December 2019 both c-sections.. well I am now 5 months pp and this last month I’ve just been feeling really off like depression and i just have random crazy outbursts.. could this be considered postpartum depression since I’m 5 months postpartum with two babies technically.

My husband tries talking to me about it but I don’t realize it sometimes so I argue and I am not a nice person to him sometimes and I really want to stop feeling this way..
