I am in the middle of an IVF cycle (had my embryo transfer last Friday (I am 9 dpo). Yesterday, I awoke to a large brown patch on my forehead. I went to my RE today who said it was "the mask of pregnancy." Although she had never encountered it as a side effect of the hormone treatments, she said it was theoretically possible since the mask is a result of elevated hormones and I was out in the sun a couple days ago. Anyway, I am not going to get my hopes up and am just going to assume it is a hormonal side effect rather than a pregnancy symptom since it seems too early for that (although I also had pink tinged CM this morning!). I would, however, like to know of any treatment for it. Frankly, it looks awful, and I am avoiding colleagues today because it is so embarrassing.
