First Timer!

So my husband and I are trying to conceive our first child. I've tracked my period since 2015 (not sure if or how that helps in any way). I only took out my IUD (paraguard) 3 periods ago. Today Im 3 days late and took my first test and it came out negative. Any advice on things to keep track of besides my period that might help us conceive?? thanks!
