You need to get help from a qualified singing teacher.

Unless of course your voice starts cracking and squeaking.

You say your a soprano your singing voice should start somewhere around Bb below middle C and stretch to Top C and a few beyond maybe an E. Is that right?

Don't believe any voice guru who tells you that you can have an extra two octaves and have a range of five octaves, this is a con it will smash up your voice altogether. Apologies about graphic language.

Excessive development of what some singers call chest voice range can cause a serious default in your first passagio. I refer here to notes below the Bb which would involve the wrongful placement of sound and the complete lowering of your pharynx. This would be you effectively puting on a voice. Your first passagio is a register change point which for a soprano is E or F above middle C. Modern day vocal coaches and voice gurus fail to accept that voices have register qualities Alto, Mezzo Soprano Soprano, Bass, Baritone, Tenor. It is annoying as many voices are being ruined via this route that you can have 5 octaves like Maria Carey or some other two bit pop singer. Believe these people and your voice will suffer from a break with missing notes which don't sound when you need them.

You need to do Cuperto exercises to retrain you in the use of your soft edge in singing.
