Im 26, have lower back cramps, period is due but im not bleeding and my breasts feel bigger. i have bad anxiety over the past month as well?

Anxious and due: Anxiety is not uncommon just before the start of the actual menstrual flow, however if your anxiety is noted throughout the entire cycle then a mental health provider (therapist/Psychologist/Psychiatrist) can help to determine its' source and if needed provide Rx. Swollen breasts due to pre-period hormone changes are also common with cramping/back pains. Still concerned? See GYN MD.
