removed my implanon!! trying for baby 4

Ti
Soo today I removed my implanon. Hubby has agreed to Bub number 4!! Sooo I have 2 questions 
1, how long after removal did u fall pregnant? Iv removed it whilst on my period and will ovulate next week. 
2, I have 3 boys how can I boost my chances of a girl lol... I know whatever il get il be happy and of course as long as it's healthy!!! But I wanna up my chances and not have a 4th boy. 
Oh and my last Bub I had GD what are my chances i could get it this time? What do I stay away from etc all I ate was fruit and healthy eating last time and still had it :( 
Wish me luck 😁
