Hi all, just wanted to share this travel tip: one pump of oestrogel fits perfectly into one well of a standard contact lens case! So depending on how many pumps you're on, one lens case could hold one or two days' worth of gel (and you could put your utrogestan in the other side). They're easy to keep clean and if you don't have lenses yourself, or know any friends who can give you their old ones, you can get them in Muji for a couple of quid. Enjoy! :-)
