Ooh I feel you, skin issues during pregnancy memang stress! A few of my mum friends also kena eczema flare-up masa pregnant, probably because of hormones and the skin being extra sensitive, one of them cupak minyak kelapa virgin je setiap hari and it helped her maintain la. Regarding the ringworm though, this one better check with your doctor or dermatologist asap because they need to make sure whatever treatment is aman untuk baby, sebab some antifungal creams kena careful during pregnancy; don't want to guess-guess, kan?
