Can we use Glycerin suppository twice a week, for my 2 month old daughter?

Hello doctor,

My two month old daughter started passing stool irregularly, from the past eight days. She was passing a lot of gas, but it did not smell. Seeing no improvement, we took her to the pediatrician, who said she had gas in her stomach. So, he gave her Decolic, Neopeptine, and Glycerin suppository. When we came back home, we applied Glycerin suppository and had an immediate effect, and she passed a good amount of stool. It was yellow in color, sticky, and semisolid. But again after that, she did not potty for three and a half days. So, we again applied the suppository today, which made her potty. Is she suffering from constipation? Is this common, as she is exclusively on breastfeeding? Is the use of suppository safe for her? Will it cause any harm in the future? Is there any permanent and natural solution?

Thank you doctor,

What if she does not pass stool for over five days, is it still normal? What does abdominal distention mean? She cries sometimes, and we immediately feed her, and she stops crying. So, it is not possible to know if there is any abdominal pain or not. Is there any way to find if she has an abdominal pain? Can we use Glycerin suppository twice a week?
