Chemical pregnancy?

Megan • 26 years old
I have been reading up on and heading a lot about chemical pregnancies. It's got me all worried. This is my first pregnancy so I hear the chances for an early miscarriage are pretty high. I have read a few places that most women who have a chemical pregnancy mistake it for af if they didn't test prior. My period lady month was pretty unusual. Much lighter than usual and two weeks late. Any encouraging above to help alleviate my fears? I am so afraid of going to the doctor and having them tell me it didn't take!
