Health plz help asap

So i've found myself needing to urinate more often but this is only after ive eaten and drunk a sip of water each time i eat some of my food as i eat during eating. I drink 8 glasses a water a day and when i just drink a full glass of water without eating anything with it i only need to urinate once after it but after eating i find myself going 3 times or more and if i drink 3-4 glasses at the same time at night i go 6-7 times as only a little comes out the first 3 times which i think is the water i drink with my tea but then after that when i go 3 more times it goes back to full glasses
SO I WAS WONDERING ...
Is this a common thing as ive only just started drinking 8 glasses 1-2 weeks ago so i thought my bladders not used to it yet BUT does anyone else think theres something wrong with me or is this a natural problem ill get used to over time
