trying to conceive

Hello, I went off the pill on September 8th 2016, mid cycle. I didn't get my period until the end of October and since then I've been pretty regular. My cycle rages from 29-31 days. Since November we have been trying to concieve and still we've had no luck. I know everyone is different, some women get pregnant on the first try and others it takes years, but it's frustrating when most of my friends are getting pregnant. I guess I just want to know how long it took others to conceive? Did you have any problems after the pill? Or if anyone has any advice. Thank you!
