I had bloods done on day 2 and 21.. I know they were progesterone and estrogen not sure if anything else was tested.. I think although the levels showed I ovulated I don't think they were high enough.. She didn't actually say why. Maybe it was her opinion and she was script happy?? Either way, it worked.. Also with your age if they fob you off, go to someone else until they take you seriously.. That's my advice anyway (I'd lie about how long you've been trying if you fall pregnant without help great, but you don't want to be fobbed off for the next 2yrs)
