It took me and my guy over a year and then the next time 2m lol Chances you are fine getting pregnant isn't as easy as what it seems the avg is about a year and half to get pregnant. Also having sex everyday doesn't help it is better to do so every three days his sperm count well be better ( that is with all guys) also your diet and his can make it hard. It seems if either of you smoke pot or if he drinks alot of energy drinks it becomes harder. I know i was unable to get pregnant until my guy stopped drink energy drinks
and i know a few other couples that have had that issue. If you are worried then talk with a doctor there are a few test for the both of you and your doctor can tell you more ticks of the trade. Anyway good luck and since you are trying make sure you are eating well and taking a basic vitamin
