Sorry if TMI!

Hey ladies, have any you ladies who are pregnant or had kids, had problems while pregnant with certain type of soaps to wash your lady part? I can't use any other type of soap other than feminine (summers eve) soap! I think my husband dropped his soap on my scrubber and Yesterday I was showering and today I noticed my vaginal area has gotten very sensitive and feels irritated. Sorry if this is TMI but I'm wondering if it's just the soap or could it be im using the wrong soap...
