Is this depression?

I feel upset and irritable very easily, especially before my period (this is when I get bad mood swings)
I've lost my first love who was a cheat, so sometimes thinking of this gets me down.
I don't have a change in appetite or anything, and when I'm not due to start my period I don't feel so bad.
However there are things that perk up my mood, so I'm not completely sad all the time, but before my period seems to be bad. So just wondering.
Yeah it sounds like it
No it's just your hormones
