could it be pms

This is my first period in a long i realized how unhealthy depo was and got off so I really don't remember what pms is like but currently ive been distant from my SO he comes home i do t talk i get in bed hold back tears and go to sleep and told how unhappy i am, weve been having a problems but they never caused me to act like this. So im in between tell him how you feel or no maybe your just real emotional right now and will regret it
