Thanks for your query.
It's not uncommon to feel itchy, particularly around your growing belly and breasts as your skin stretches to accommodate them. Hormonal
changes may also be partly to blame. It usually disappears right after delivery.
But you should remember severe itchiness in the second or, more commonly, the third trimester can be a sign of intrahepatic cholestasis
(ICP). The itchiness can be extremely intense and is typically worse at night. This ICP has very bad effect on fetus.
So better to visit your obstetrician first and if he/she suspects, you should do a liver function test with special mention on bile salt and acid and also frequent Ultrasound
monitoring of the fetus to see his well being.
