Late period

Tiffany

I been late over a week now and I never been late before so I took some test at home and they all came back negative. I also went to the doctors yesterday and got blood test done but it’s negative too. All the doctor said was wait a few weeks or till my next period and see if not they’ll give me medication to help bring my period down. I never been in this position so I don’t know what to do. Anyone got any tips?
