It would be pretty rare to get pregnant your first time trying. It can take several months. If you don't get pregnant within a year you should talk to your Gynecologist and get some tests done on you and your husband.
I would recommend getting an ovulation kit. You can track when you ovulate and have intercourse a couple of days before and during ovulation.
We just got our first positive pregnancy test (Jan 2017), and we started Jan 2016
It can take a year sometimes longer to get pregnant don't be discouraged because it didn't happen the first time.
