Mood swings

Okay girls, my period is due in 5 days and my mood swings are on one today. Literally i think I’ve caused about 3 arguments with my other half already and he hates it when I start unreasonable petty arguments, like me too I hate arguing. I argued last night because he didn’t say night properly, argued with him this morning because I thought he was ignoring me and literally blew up his phone and then just started another one because he’s going out tonight with loads of lads and didn’t reassure me. Like WHAT IS WRONG WITH ME. I need some advice to stop causing petty arguments and how to just chill and be laid back in this relationship? Because I’m getting so over protective and clingy and constantly messaging him paragraphs of bullshit all the time moaning about something😫 Helpppppp!!
