Can I get out of a prenup if I was forced to sign it?

My husband and I are getting a divorce and we have a prenuptial agreement. I only signed it because he told me he would not go through with the marriage if I didn’t. A lot has changed since we got married, including him getting a much higher paying job and me leaving my job to raise our two kids. I waived alimony in the prenup and that just doesn’t seem fair at this point given what he earns. Is there any way for me to overturn the prenup and get a more fair divorce settlement?
