What should I do

Nana

My 6 month old was with his dad over the past week, and he came back with me today and has been very grouchy. He’s been with me since 8:30 and has only peed about twice. I’m not sure what it is and I’m very nervous. I wanna go with my gut and take him but it’s so late and I’m pregnant so at the moment I feel extremely sick. Please help
