I currently have my my period but woke up and had morning sickness, also have a cold, should i be worried about pregnancy?

Viral symptoms : Your "cold" or virus can also make you feel nauseated, I wouldn't worry

If you engaged in: unprotected sex and have missed period - would take a home pregnancy test. Normally, classic pregnancy symptoms don't appear until a period is actually missed. Your nausea could be related to your period or to your possible infectious illness.
