extra fluid

So last night I went into labor & delivery for contractions (they weren't strong enough sadly) & was about to get sent home but my baby was showing a little lack of oxygen on the monitor so we had to get an ultrasound & she had to pass some test which she did she got 8/8 which was good & her oxygen levels came up 🙂 but before they sent me home they said I have an extra amount of amniotic fluid & need to make sure I mention it to my doctor on Tuesday which I'm sure it's fine or they wouldn't of let me go home but has anyone else been told that ? Was everything fine ?
