Overreacting.

If there were anything wrong with your baby, would they catch it before the baby is born or is it mainly afterwards? Either way, I'd keep my baby and love her just the same but it is something that worries me sometimes with this being my first child. I've never been a kid/ baby person until last year when I really started seeing myself as a mommy. I did get a test where they drew blood and checked my baby for abnormalities. They said if there was a problem they'd leave me a voicemail and if I didn't receive a call everything was normal. Well I never received anything so I'm assuming everything was normal. I have 2 months till my baby arrives and I guess I'm just starting to overthink everything. TIA for any advice!
