Help!

I am in a dilemma and I need some advice, I have 5 months trying to get pregnant, our plans were to try until June, but as nothing happened we decided to try one more month, I did the test but it came out negative, the problem is that our wedding is in June 2019 and I am struggling thinking about my wedding dress but I also do not want to stop and try again in one year, in 4 months I am going to turn 36 and I am afraid that my time of getting pregnant is less, what I do? I keep trying or wait after my wedding?
