Trying to conceive first time

Is it possible to get pregnant the first time trying?! I have a wedding I'm going to be in and I want to have a baby at least 4 months before so I hVe some time to get back into shape this likely at all? Me & my husband have never tried yet but I have been taking prenatals and folic acid for about half a year now. Is there anything else I can do to increase the likelyness? I find that even using this app is teaching me a lot!
