AF 11 days late

Took the last pregnancy test we have in the house praying this one doesn't come back negative! Drs appointment Tuesday to see what's going on. Should I request a blood test while I'm there?  Anyone else ever been in this boat and been pregnant? 
**test was negative 😩😩😩 will be checking with dr for a blood test. Have had watery and creamy cm almost every day since af was suppose to start**
