I took a test and it told me i was not pregnant. My period was supposed to start today but it hasnt. My symptoms are headache, bloating,fatigue,nausea, i feel very off, im having cramping and i have tender breasts. I never felt like this before my period started. I am on the pill i just started this month. And i had unpretected sex when i started. Im so confused and frustrated. And i did take a test. If anyone has any advice about this please help me.
