Urge to urine but less urine. Inside.

Week 1 In the initial 3 days or so I have urge to go to urine many times From day 4 or 5 it's raining here heavily for 5days  so the problem continued I'm not drinking loads loads of water to go those many times daily 4-5 times and specially before sleeping it's horrible of which no propper sleep 7th day same my stomach is feeling full and when I go I'm getting less urine but the feeling will be like as if bladder is full. Urine colour is just yellow not dark yellow. Could anyone tell me what is happening. The area two inches below belly button there I think I'm feeling something is heavy or full and running to washroom. In between my motions are mushy type for some days and for two to three days I went to motions repeatedly three times I don't understand what is happening inside.
