So on Friday the 4th of November I experienced really bad stomach pains and diarrhea. The following weekend I was fine until Sunday night when I felt ill again. (After I had diarrhea for one day I didn't need to poop at all and I didn't actually poop for 3 days, I felt constipated). I was then ill for 3 days having stomach pain but didn't have diarrhea. My stomach ache stopped when my period came and I had my usual period pains instead. But now that my period has finished I am experiencing diarrhea for the second time. I had it badly yesterday and I haven't had any today but maybe that's because I haven't ate yet. I rang my doctor and they do not class this as an emergency appointment so I was told I couldn't get a appointment until the earliest of next week. What shall I do in the mean time? Does this sound serious? What foods shall I eat while having diarrhea?
