Your gynecologist is right to wait, its probably too soon to test yet, 3 days is very early to know if its doing anything, is this your first hrt, or were you on anything before the gel, it's good you are under a gynecologist and you are being monitored, given you are at a private clinic I would be reassured they know what they are doing, unlike the NHS where its not so good regarding hrt, side effects will be different for everyone and won't affect you the same way as they do me, you are also on a different regime to me, I use estr but not testim, when I first started the gel, my side effects were nausea, headaches, increase in hot flushes and increased anxiety like a strange jittery feeling, but they settled after a couple of weeks, I get them back when I change doses, going up or down, I've found it hard to find a balance, but that doesn't mean you will, its so early on for you, 3 days definitely isn't enough time to deal with the anxiety be patient and I'm sure you will feel the benefits in a few weeks, good luck.
