Need someone to talk to ???

Please help, me an my boyfriend are trying to concieve before he leaves for the navy and he leaves in three months. We are planning on doing a civil ceremony as well to get married before he leaves. We've only been trying for 3 months, I was on the pill for 4 years then implanon for 2.5. I'm worried that might have something to do with it, but I just need some encouragement right now. I'm scared I am letting him down and its a lot of pressure. I've been really sad lately and cry a lot an he says it's okay but I just want it so bad an I have no one to talk to about it.
