A regular expression which will match all Or, It and And words in the string without . or : before these words

Question

I am looking for a regular expression which will match all Or, It and And words in the string without . or : before these words.

For example I want the following behavior:

• ". And", ": Or", ". It" --> not match
• "And", "Or", " It" --> match

It quite easy to get opposite result. This (:|\\.)+ *((\\bIt\\b)|(\\bOr\\b)|(\\bAnd\\b)) will match ". And" and will ignore "And", however this is not what I need.

Any help is appreciated!
