I get into a fight every time I'm on my period??

So me and my boyfriend gets into a fight pretty often over silly things mainly because I am a very jealous girlfriend. I know I shouldn't overreact but sometimes I can get a bit crazy.

We got into a huge fight yesterday and today I got my period. It got me wondering if it's because of my PMS.

So since I have a diary, I looked at the dates of when me and my boyfriend fight then look at logs I put on Glow for my period.

What I found was surprising. We always fight about 1-3 days before my period or during my period.

Do you think this is a coincidence or me being super sensitive during my period might contribute to it??
