It's my first month of using oestrogel and pills (swapped from patches) and it says the gel pump contains 64 metered doses. I use 2 a day so that's 32 days......but i've used it for 34 days and it wasn't empty, I'm sure I'll get today out of it too. Is this normal? It pumps easily so i don't think I've "under pumped" and I've definitely not missed a day and have only got 1 bottle open.
