Seeing your entire chart would help. In general, when we have a stellium in a house, it means a lot of action will take place. Lots of events will relate to this house. This is not bad.

So take advantage of the good times, e.g. save money.Should I be worried that I have my sun,moon,Venus,Uranus,Neptune in my 2nd house Sagittarius.
