Help me!!

Kayy

Okay so I had my period June 20 and usually it would be around 30 days and if late around 32 days this year. Idk how long my cycle is sometimes. But for the past couple weeks I’ve been having symptoms and I thought it was my period. It has been 3-4 days late now I took a test and it came out w a faint line but I still have the same big belly as I’ve had before.what should I do??
