That's disappointing @Tilly198699
Your GP should have advised you to increase the gel until it controlled your symptoms, giving each new dose a few weeks to take effect.
2 pumps is really the minimum dose. (although some women find 1 pump is ok.)
For women like you in their 30s, you tend to need far more than older women, eg in their 60s.
Just for the record, the amount of estrogen in 1 pump is 0.75mgs.
So 2 pumps gives approx 1.5mcg estrogen.
The entire content of the bottle is 80mgs/mls but most of that is water/alcohol as the base.
I'd see your GP and ask to increase it. This guidance is on the leaflet in the pack.
You might like to know about the Daisy Network which is a national charity for women with early or premature menopause. They offer support, info on their website and have a forum.
I'd caution against adding progesterone at the moment as it will just confuse matters. You need to get the estrogen dose right.
The addition of progesterone when you have no need (no womb) is controversial and not one suggested as the 'norm'. It tends to come from the US and is not mainstream treatment here.
