Eagerly trying!!

I’m 39, I have 2 children 17 & 11 years old from a previous relationship & my new partner also has a 10 year old from a previous relationship. We pretty much fell in love instantly & knew we wanted to be together & have family so I came off my coil in July 2017.......(I had this in for 5 years)

We are a very sexually active couple....sometimes 3 times daily when we are child free!! Is this period of time normal not to fall pregnant or am I just too impatient?
