Aah, white blood cell naik sikit during pregnancy tu memang normal sih, tapi since yours keep rising from 14 to 18, better check with your doctor just to be safe, mungkin mild infection or maybe just your body reacting to pregnancy, but best to get it confirmed la. A few of my mum friends had similar situation and when doctor check properly, ada yang kena mild UTI or thrush (which also explains the itching!), so worth investigating sebab baru 5 months lagi kan. The dry skin and itching boleh je pakai moisturiser yang pregnancy-safe, tapi do mention the fever and itching pattern to your doc just in case, okay?
