Diarrhea in early pregnancy?

Sara
Was wondering if any of you had diarrhea in your early pregnancy.i'm four weeks and four days and had diarrhea for I guess would be almost a week.Maybe it's hormones I did have IBS before I got pregnant.just wanted some other input.Looked it up online and there was so much conflicting information.I haven't been to the doctor yet he won't see me until eight weeks.
