No. But I suspect that there is something more to your question - what lies behind it?

The probability of an event can never be negative. This makes sense as probability is informally defined to be the likelihood of an event happening, and if it definitely will not occur its probability is 0 i.e there is no likelihood of its occurrence

For the question I did on continuous random variables, I obtained a negative value from integration using natural logs.

Then your calculation went wrong somewhere.
