Hi I've Been Experiencing Weird Bowel Movements For Over 2

Hi

I've been experiencing weird bowel movements for over 2 weeks now.
It started with diarrhea... My movements have more solid shape now, however... I've missed my period and I have dark urine.
This morning it was sort of brown...
I've also seen a very faint tinge of red after wiping... I'm not in my home country right now, but what is possibly going on with me?
