I always get diarrhea the couple days before my period. I had to stop reading side effects of medicine because I imagined them. If its time for your period, then dont worry. If it would help to ease your mind, call a doctor but Im sure its nothing to worry about. Remember, a lot of things cause diarrhea including stress.

Classify if it is truly diarrhea. Loose bowels from menstration is different.

Diarrhea is going 2-3 times an hour with no form (liquid).

So if you are truly having diarrhea, call the office and state so. They will either tell you to discontinue or to take anti-diarrhea medicine.

I do the BRAT diet (Bananas, rice, applesauce, toast). It works! And the potassium from the banana helps with cramps :-) You might try that for the next 24 hours and see if it makes a difference.

I get the same thing with my period so I know it's hard to tell the difference. You could call your doctor to ease your mind and maybe they could give you advice as to at what point do you worry. Also in the mean time maybe drink things like gatoraid to get some extra electrolytes in your system, along with regular fluids, so you hopefully don't end up feeling worse. Good luck.

I was on ceftin, and this happened to me, but I know it's dangerous to stop an antibiotic before you take it all, so I just kept taking it. I had diarrhea for 10 days, but it wasn't debilitting or anything. Next time I needed an antibiotic I told my doctor "no ceftin, I got awful diarrhea from it" and they just wrote that in my file and gave me something else.

Thank you everyone! I do feel better and i talked to my mom as well. I also got the courage to read up about to see what is considered severe etc, so today went and Its normal. But still no period, ugh! I wish it would just come and go already.

A great remedy for diarrhea is turmeric. Teaspoon of powdered turmeric in water and chug it back or sprinkle on food OR you can take it in concentrated tablet form. I take turmeric caplets everyday and I use it on my food. It is good for health in many ways.

I hope you feel better and things work out. Also remember Eat plain yoghurt With active cultures or take probiotics because of the antibiotics strips all the good bacteria away too.

I work with antibiotics and diarrhea is a side effect. The antibiotic messes with the normal flora, so most people experience some issues. It is a problem when the diarrhea goes on for days and after antibiotic. I also get the issues before my cycle, so you are just getting hit with a double whammy.
