Period struggles in relationship of 5 years

Hi everyone, me (F17) and my boyfriend (M17) always struggle around 3 days before my period and 4 out of 7 days during. This has always been the case where we feel a little distant and I do or say things which upset him and I don’t realise I’m doing them. It‘ll be little comments about him or my tone generally which will upset him.

I track my period which has helped slightly but I get really emotional and snappy during this time which distances us and we’re always both so upset. Him because I’ve hurt him and me because I feel so guilty and like it’s out of my control.

I love my boyfriend the other weeks of my cycle and it can be hard to plan ahead with how to cope because I forget how extreme I feel.

Does anyone feel the same way and how do you fix it or stop it from occurring as much? I am thinking about birth control as I’ve heard how different forms can improve my mood but I’m scared of the side effects. Is this normal or should I look into having PMDD but I don’t want to self diagnose?
