Itchy bump at third trimester

Hello. Im at W32 now.. I have been experiencing severe itch but only at night. Usually it last 1-2 hours and may spread to legs and arms. Does any other mum experience this too? I applied a lot of oil to moisturise the bump. Bio oil, clarins, mama’s choice stretch mark serum and cream… but it is still super itchy! Been experiencing this since W28 or so. #adviceplease #FTM
