Sonia, I think that it'll be nothing to worry about. I had the bright red bleed that came out of nowhere, and they never really found a reason for it. You've been prodded and poked down there, and then with the bd'ing on top of that, I would hazard a guess that it's just a little bit of cervical irritation. The epau said to me that it just happens sometimes, and if it's pink or brown it can even just be left over from your last period, and is expelling itself from your body.
MissM, we were looking at the Trider before we got our bfp, I like it in the greeny colour (is it called chiffon or something?) I've never seen one in the flesh though. I think we're looking at getting the Quinny Moodd.
