Advice wanted

Hey so I have soccer practice all this week and I'm starting my period tomorrow but my second and third day are usually the worst. There's no bathrooms out by the fields and practice is only 2 hours long but I'm not a tampon girl. Usually I'm just lucky and my period and soccer don't cross paths or it's the end of my period and easily manageable. I really don't want to leak during practice does anyone have any suggestions as to what I should do?
