Tips for what worked while TTC

So me and my husband have been TTC for almost 8 months now, we've tried Preseed and had no luck. I'm taking prenatal vitamins daily and tracking my ovulation and everything. My question is for everyone that struggled to get pregnant, what worked to help you conceive? I feel like my husband and I are starting to get stressed because its not happening which doesn't help the situation, so also any tips on how to help with stress?

Thanks in advance! 😊
