Okay my period is about a month late. I am very confused because I have never been irregular and my body is very predictable when it comes to my period. I haven’t had sex though. So I know Im not pregnant but Im just very confused about it being late. I’ve had all the symptoms for the past few weeks like Im always hungry, moody, emotional, tired. Im not sure if I should be concerned or is its not a big deal if I miss a month or what? If I missed a month then should be starting my next period within the next week.
