Metformin meltdown

Question for the ladies taking metformin. So I started the night before last I woke up with server diarrhea sorry TMI I thought it was the food I ate yesterday I couldn't really eat because the smell of food made me sick to my stomach. I don't really have an appetite. Has this happened to anyone else? I aslo am taking 2.5mg of prednisone every night. Some help!

Update: so now I'm laying down and I feel a gush of fluid it's like water and clear ovulation day is tomorrow is this a good sign. I also take the conception pills.
