Re: Precum: Worried.
I had an issue like this about a month ago. The emotional stress I was under caused me to feel sick in the morning. However, the stress also made my period come early. But you are right that the stress can mess things up in other ways such as making you period late. The nausea could be from many things. But so far if that is the only symtom you are showing I would find it safe to say that I do not think you are pregnant. Take a test if you are still worried!
