I'll be getting mine this week. Because I refuse to go on the pill (stubborn I am) I've had to wait till the middle of my cycle, so I can get a bt to confirm I am not pg, then I get to have it. I'll have the bt tomorrow. Can you ask for that instead? My dr said it's important to know that you are not pg before getting the booster.
At this stage, Heath and I are thinking of starting to try in December or January. If we start too early, there's too much of a chance of having both babies born in August!
