Four

The number of days since transfer.

The number of times I had to get up to go to the loo last night.

The total number of embryos we've had transferred in three IVF cycles.

The number of gestone injections I've done so far - and last night I discovered that although the ice does numb the skin and prevent the needle hurting as it pierces the skin, applying heat to the area instead of ice before doing the jab makes it less painful to actually squirt the stuff into the muscle. I'm pleased about that, since I'm hoping to be on these gestone injections until about 12 weeks (see that blind optimism again?).

The number of times I have to take Ritodrine a day. OK, the gestone hurts, but it's the Ritodrine I really hate. For over an hour after each dose, I feel anxious, shaky and sometimes a little bit dizzy. Fortunately, apparently this one doesn't go on after test day whatever the result. Also fortunately, two of the doses are taken while I'm in bed, and I can (try to) go back to sleep afterwards.

The approximate number of mood swings I have each hour. Lucky, lucky DH!
