We can't be sure, and we don't even have any good guesses. The current best guess was just recently revised by a factor of three, tripling the number of stars in the universe to 300 sextillion, or 300,000,000,000,000,000,000,000.

The problem is that there are probably more stars even than that, because so many of them (and we CANNOT KNOW how many!) are small, dim red dwarf and brown dwarf stars, which cannot be seen even up close.
