Hello,
One of the possibilities that can present is prurigo of pregnancy which can involve any body part and can appear in pregnancy. The other possibility is of prurigo gestationis.  No treatment is effective and medicines are to be taken with caution because of their adverse effects on the fetus. Avoiding hot water baths and applying plenty of good moisturizers and calamine lotion helps in relieving itching. Gentle moisturizers should be applied immediately after taking baths. If the symptoms persist then liver function tests need to be monitored.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
