Amy- You can fall preg straight away, i had mine taken out on Jan 6, hadn't had my period since start of dec so i was due for it, didnt get it til 27th Jan and i ovulated 17 days after that (normally you ovulate 14 days after) and we fell preg first try, so basically as soon as you get your period count 14 days from that day and you can start trying... or maybe a start trying at 10-11 days to be sure you dont miss it. I got the tests to confirm when i ovulated, its kinda like a preg test the ones i had, you just dip the lil stick in your pee and it tells your pos= yes your ovulating, neg= no your not.
Are you trying for a boy or girl??? or not bothered?
