any tips for trying to conceive for first pregnany

So my husband and I have been trying to conceive a baby for about 3 months now. And was wondering if any of you have any tips on how to get pregnant. I took a ovulation test today and it said no. But does that mean that I haven't already ovulated a week ago?? My husband and I have been having sex almost everyday. And I'm showing some signs that I could be like cramping and cravings my period ended last Saturday. So any advice??
