Talk to Gastroenterologist on Stomach Issue

I had stomach infection, uti and yeast infection one after another around 7-8 days ago. I was taking flagyl, ciproxin and diflucan for these problems. I also have anxiety so sometimes I have the urge to rush to the washroom to pass stool which is gassy. Now it’s been a week since the antibiotics stopped but my stomach isn’t normal like sometimes it’s runny sometimes constipated but mostly soft runny stool. Today also I had normal stool and then within a few minutes runny stool. I am taking ecotech probiotics since 4-5 days. I am also having a lot of belching like burps on empty stomach and tenderness in the lower abdomen area. I remember my doctor once gave me colofac for belching and pain in the upper abdomen and also motility of the stool. But this time the tenderness is in the lower abdomen. Can I still take colofac 135 twice a day for two weeks? Is it happening because of the antibiotics or anxiety or is it something else? I also had a history of labio anal fistula 5 years ago whic
