Not sure?

Abby

I've missed my period by 14 days, going toilet a lot, 4 days of diarrhoea & constipation, urinating a lot, had 2 days of back pain on right side, nipples are sore, and having different vaginal discharge, feeling lazy, tired, and sometime less eating or more. What is happening? I'm concern and 100% I ain't pregnant. Help me please
