Imodium and toilet

I am a woman aged 57 and had severe diarrhea during the past week-end. I started to use immediately one imodium pill after a bowel and then another pill after a second bowel. Since then, I still have a serious constipation for six consecutive days, during which I have gone only once in two different days to the toilet, and the results have been two small and hard excrement in those two occasions. Today is Sunday and I can not reach a doctor, so please, inform me what can I do about it now. I will be very appreciative to you for it. Thank you very much in advance for your prompt attention. God bless you! (E-mail: sSonia427@aol.com
