Just had a baby and SO feels neglected .. HELP.

My baby is 6 weeks old .. I'm not depressed or anything but I have post-partum hemmehroids , sleep deprivation ( some nights) and my body and hormones are still out of whack. Some days I feel really annoyed with my SO . Lately he has been feeling neglected and that I dont love him.
Im seriously stressed because I dont know how to explain this is not the case. Can anyone help? Is there any articles that explain why women are this way?
