Sorry to hear about your chemical preg. I know some people prefer not to test early as they'd rather not know (and I can see the point, as the m/c rate in the first couple of weeks (round about your period due date) is very, very high, more than half even in younger women), But my view is, I want to know! I've had several chemicals myself, and I try to take the positive from that........I'm ovulating, and DH is fertile, and one of these months it will happen for real.
Good luck for next time.
