Relationship after baby?

I'm a FTM pregnant with a baby girl. My SO and I have had our ups and downs like any other couple, but we've always pulled through and we love each other a lot. This will be our first child. Im a little worried about what life will be like after she's here. I know we're both so excited, but does all the stress of a newborn cause arguments? Did you feel distant from your SO? I just wanna make sure that we don't drift, TIA
