Sorry to just put it all out there but i need answers ASAP!! My last period was December 12 till the 4th. I had unprotected sex on the 12. I had flo tracker and they said my period should start on the 19th its never came... I’m scared to get a test because i am young and don’t know how my family will react. I have cramps lower stomach, get nauseous, my areoles are getting bigger and darker. I was thinking if my period doesn’t come next week to then be worried. Pleat help!
