Can hormones be excuse for any behavior?

So I was reading on some Serbian web site two different situations and they are connected with pms and pregnancy hormones.

First : Wife is 4 months pregnant and he understands hormones,mood swings but she almost hit husband with glass because he brought her peach juice but instead of orange.He is good no injuries but wants to divorce because pregnancy can’t be excuse for violence.

Second: Girl almost strangled her boyfriend in pms.He left apartment and broke up with her.She called him and called he doesn’t answer.But she is one that is mad because he can’t understand she was in pms.

So can hormones be excuse for this kind behavior?

I know that women’s are not same when comes to pregnancy and pms honestly this is to much.
