I'm 31weeks tomorrow and the toilet is my enemy!

Is anyone else getting the constant urge to go to the toilet about 20 times in the night (nothing unusual I know and was fine until last week) but as soon as I sit down to go my little one seems to kick me down below so I can't wee!!!! Wtf it's so annoying I don't have a water infection and am drinking about 6/7 pints of water daily! What's going on? Any ideas? 🤷‍♀️😩
