I am 7 months pregnant and I'm attending a university and geiting financial aid through FAFSA, I just wanted to know if my absences from my delivery will affect my financial aids since I would probably miss school for a week or two after I have my baby.

You will need to discuss that with your university. The FAFSA doesn't monitor your attendance. Since you only complete it once a year in the spring, you should be back at school. The issue will be with your professors and your absences from class. Make sure you speak with them soon so you can get your assignments completed in advance or get an extension of time.
