why wax your eyebrows? is messy, does not get all the tiny hairs and takes the top layer of skin off. try threading instead - painful, but gets rid of all the hairs (and only the hairs!) and lasts just as long. �5 in my local salon...is super! have it done every 2 weeks -4 weeks depending on growth and pluck inbetween. perfect.
Try an ibuprofen next time before the wax. It helps a lot.
PS I am on the Depo Provera shot and don't get a period either. My doc, who I trust cpmpletely said it is OK. I was off it a while but it's so bad I went back on just to stop the period.
