Wanting to start TTC!

Hey y'all!
So I finally got my husband on the band wagon of trying to conceive our first! I'm so excited and yet nervous. I was just wondering if any of y'all have any tips or tricks on what I need to get started. I was thinking about buying some ovulation tests to help guide me along when I'm ovulating etc. Any information would be appreciated! 
Side Note; we have been together for three years now, never used protection or anything and have never gotten pregnant unfortunately. Ive always thought there was something wrong with me lol but I figured it just wasn't the right timing for us. So if y'all have any info about anything whether it be testing, tracking, positions etc I'd love to hear it.
Thanks so much! ❤
Another side note; this is what my tracker is saying: I just had my period and apparently I am in my fertile window starting today. I don't want to stress about it but I also want to take the proper precautions to help make it happen.
