Help TTC

Okay hi my name is CaSondra me and my hunny has been together for a year we are getting married in july. He has kids himself and I have a 2 year old daughter, we are trying to have a baby together. I had nexaplan implant for the last two years since my daughter was born and I got it removed march 23. We have been having sex a lot and I ovulated all last week took two pregnancy tests and nothing. Any ideas how to get things going and any advice how long to conceive after nexaplan removal. Thank you so much in advance
