Recently I've been getting unusually grumpy, irritated, hungry and tired. I get angry at my husband for doing or saying stupid things and throw a little fit and after 30 min of cooling down I hit a sad stage and apologize to him for acting irrational and all while doing this I know that I don't actually want to but I can't help but feel upset and somewhat annoyed inside. I'm not even close to my period. Starting to think it's stress, has anyone else experienced this? Any advice?
