Trying to have kids

Me and my wife just got married not too long ago and we been trying to get pregnant ever since we got married. My wife is feeling so many things that she never felt before. She been taking tests but came back negative. We know that’s too soon to know something because we are impatient but more excited that we are trying to have kids. Her period is coming up soon and we’re praying that she misses it but we can’t say for sure. We honestly need some advices and even some guidance for this because this is our first time. Thank you in advance.
