Hi tjsmith
I think it depends how long you have been on them, have you just started them? Or been on them for several months?
I am on the evorel sequel ones, they do start working pretty quick so I guess if you've not been on them long and suddenly miss one I guess it too could leave you with less hormones than you have been starting to get used to.
I'm sure when you put your next one on they will start to make you feel better again quite soon.
Let us know how you get on
