Diarrhea! positive!

April 11 to April 13,I have diarrhea every morning and night. Sorry for tmi. I'm waiting for my period this coming April 15. My pee is smelly and bubbling. I don't know why? I'm confused. Well,I just used the pregnancy strip coz it's just a dollar anyway. And ended like this. Is this real?coz I'm still waiting for my period.
