Is diarrhea a early preg sign?

The past 5 days ive been very nauseous and been puking in the morning and bad diarrhea ( loose watery kind). Im in the bathrrom AT LEAST every 10 to 15 mins. Ive tried everything and it just wont go away. Im ttc but glow says i shoukdnt ovulate until tomorrow. All though last month glow was off by a week. I guess my question is has anyone else had these symptoms and then got a bfp?
