I need some comfort

I got off my IUD July 2017 or so and my boy friend and I have been trying to conceive since. We don't use condoms, I love having sex, so we have sex about 3-4 times a week and maybe twice a day sometimes....

Anyways, I haven't been on the IUD and I can't seem to get pregnant. I heard some people say it takes awhile seeing how I was on the IUD for 2 years. I'm 27 and my boyfriend is 32 and I'm just freaking myself out that it's not going to happen.
