Has anyone ever had nexplanon?

I’m trying to get pregnant and don’t know how long it could possibly take

My first I was 15 had it in for a year and a half. Tried for 4 months to get pregnant and failed.

Put it back in sep 2017 and had it removed December of 17 got pregnant January of 18

Now I had it in January of 19 and just had it removed august 2nd and I’m currently trying to have another child but I’ve also had 2 stds like Chlamydia and Trichomonas. Which I know those will cause troubles getting pregnant.

I’m really scared and have a big phobia of throwing up which I don’t know how I handled pregnancy the first time but I’m desperately wanting a second because I’m done after the second so I want to get it over with.
