Not a massive thing but at 14 weeks I developed this painful itchy chapping around the corners of my mouth. Mentioned/showed it to my MW at my next antenatal appt and was brushed off with "oh ask your GP, if we refer you to a skin clinic it'll take ages". Well, it's only chapped skin and I'm not going to take any medication when I'm pregnant anyway so I didn't bother and then recently (I'm 29 weeks) it cleared up by itself.
By the by, my 28w blood test last week showed anaemia and I got prescribed iron tablets for it, started taking them, oh, about the same time my skin started to heal. Idly looking up anaemia on the NHS website I find that one of the signs of anaemia is angular chelosis... chapping at the corners of the mouth.
So I've been anaemic for 14 weeks, and I mentioned this skin thing to my midwife, and it's a blooming symptom of anaemia, which they specifically test for because a) pregnant and b) having twins so blood volume has increased by loads, but she didn't twig.
Luckily it's one of those nutrients where the wee ones get their share, and then mum is last in line... but no wonder I've been so knackered for the last 3 fecking months. Out of breath walking to the train station in the morning... blood roaring in my ears at night. All avoidable.
