Taking out BC soon... Ugh!

Kimberly
My hubby is unhappy with the way the Nexplanon is affecting my system. He hates that I have no sex drive.  I love that I don't have periods, dislike the weight gain, and the pregnancy symptoms. We are a blended family. He has custody of his 4 kids and I have custody of my 2. 
He wants me to take out my BC. We do want to have a child, just one, to kind of unite our blended family. He came from a blended family too. 
I am normally a nympho when it comes to sex. Lol... He thinks that with how often we have sex right now it'll take me a while before I get knocked up. I just laughed. What happens when a nympho gets off her sex drive killing BC? I don't think it'll be long before I get pregnant.
