Hiya
Just some advice I started my period 10th December roughly lasted 7-8 days, last had intercourse with my partner 4th Jan no protection or anything and now I am late for my period I have done a test but I left the urine so I'm not sure if I made it invalid any advice is there still a chance? I've been extremely tired, terrible back ache I've had, been super cold flu like symptoms so not sure
