30 weeks pregnant my nipples and areola area or skin is very dry and rough what should i do can i use olive or coconut oil for massage or something el?

YES, or Lansinoh ;: Both olive ; coconut oil are safe to use for massage ; will probably help. Calendula cream is also an excellent choice, as is lansinoh- see https://www.Lansinoh.Com/products/hpa-lanolin i also advise you take a purified fish oil rich in dha, which often helps dry skin and is very important for development of your baby's eyes and nervous system.
