I had the 21 day test thingy done with my GP, and they said that was fine. Maybe I'm just being paranoid and negative. I dunno. They said to come back to them in the Spring/Summer if I'm still not pregnant. But because I'm the most impatient person in the world, that seems like ages away to me!!
I've ordered some of that pre-seed stuff though, so we'll see if that makes a difference this month *fingers crossed*
