Advice about miscarriage please

So I have a little girl who will be two in February who I tried a full 4 and a half years for as I have pcos... last month found out I was pregnant again which we were delighted about but it just wasn't meant to be as I lost at 5 weeks.. very disappointed but only reason I'm not wrecking my brains is just that it wasn't meant to be this time.. so how did you all manage with it and how long did it take you all to try again when's yo soon or just general advice needed thanks in advance xx
