Missed period and vegetarianism

Hello everyone, so this year I began my vegetarian journey and my concern is that it’s causing my cycle to become late. I got my period in December on time but this month I am two days late. Has anyone else had this problem or know any solutions? I’m not stressed and I’ve taken pregnancy test but they have all been negative. Pleeeeaase help!
