I Haven't Been Eating Or Drinking Water A Lot Lately.

I haven't been eating or drinking water a lot lately. Maybe like 1 small meal a day, I know it's not healthy but I'm having financial problems so I can't buy food or water. I noticed I have been having a lot of clear watery discharge. Does that have to do anything with me not eating or drinking water or do I have an infection? I thought I was on my period but my period ended last week Wednesday. Yesterday the discharge looked a little pinkish and today it looks like a extremely light yellow. Really really light yellow.
