    20 week scan

    We have our scan tomorrow, and I've lost the piece of paper with the instructions on plus can't remember from last time - but do I have to drink a litre of water in the hour beforehand and no peeing?

    TIA

    I'm not sure, a mate told me that was only for the earlier scans.

    sorry, not much help, am I?

    Babys a lot bigger now, much easier to see. I did drink b4 hand.....not a litre by any means...defn not as much as with 12-14 wk scan. Infact, i think with #4 i was in such a hurry, i had my morning coffee, then scooted to the ultrasound place......

    I was told empty bladder an hour before then drink 600ml water over the next hour and hold
    So if your app is at say 11am, then you would empty at 10am then start drinking the 600ml over the next hour no need to skull, and don't pee.

    Im pretty sure it is only 500mls for the 20week scan. Dont quote me but I know I certainly didnt have to drink a litre.

    Hay,

    my instructions ,us on monday, say pee about an hour before and then drink 4 cups so 800ml -1lt and not pee again, now if you ask me that is a form of torture, but for the 13 week scan I had I tried, now while waiting for the scan, I just went nup, I can't wait any longer and if I don't go now I might pee my pants, so I went, and then downed about 2 cups of water before the scan, no complaints from the sonographer.

    I think the best thing is to just make sure you stay hydrated, and take some water to the appointment, 'cause you will probably wait for 15 to 30 minutes for your scan anyway.

    Enjoy your 20 week scan. I almost cry when I see that baby, and the heartbeat, and then they move, and you can see the fingers & toes, oo it makes me giddy thinking about it.

    I had mine on Tues at 11am and they told me to empty my bladder at 9.30am, then drink a litre of water before 10am and hold it til the scan. This is also what they told me to do for the 12 week one. Pure torture I reckon! My Ob had told me to make sure my bladder was really full for the 20 wk scan too so they could get a good look at the placenta?

    Wish I knew if I didn't have to drink the whole litre because I was pretty uncomfortable but the sonographer let me go to the loo about half way through as she said the rest of the measurements could be done without a full bladder?

    Sorry I couldn't be of more help but good luck and enjoy

    This reply might be a bit late.

    I was told just to be well hydrated and try not to go to the toilet for an hour before the scan. Not to hold a specific volume like they need you to do at 12 weeks.

    i've had heaps of ultrasounds before i was pregnant and i had to do the drinking thing - at least a litre.... for my 20wk scan i haven't been told to do anything... so you shouldnt have to.
