Late period

Janie

So my period is 5 days late, which this has never happened to me before. I’m scared. I took a pregnancy test but it came out negative, so that takes away the option of being pregnant. What I’m wondering is, Can I have a missed or delayed period because of my weight? I’m usually around 135ibs but recently I dropped to 126ibs in the past 2 weeks. Could that be a factor to my late period?

Please comment what you think!
