I might have appendicitis but I m not sure. I had my period last week for the first time in 6 months and I have been very heavy (not pregnant, just irregular). I noticed I have been constipated and haven t had many bowel movements for the past 3-4 days, maybe just one a day. I am not nauseous, I m not vomiting, I don t have a fever, I can pass gas just fine. I have slight discomfort on my right side, right where my underwear begins. But it s fine and not bad at all. It just worries me. My appetite is fine, maybe slightly less that normal, but that s usual during my periods.
