Advice. TTC. FTM

Destiny • 22. Married for 3 years. TTC since Oct 2014. Miscarriage in May 2015. Got our positive for our rainbow in June 2017! Expecting our rainbow miracle March 2018! ❤️🌈
Hi. My husband and I have recently started TTC. I will be a FTM and I'm looking for advice, tips, and tricks on what y'all have found super helpful in your TTC journey.  Are you temping or using OPK's? Has anyone found temping or OPK to be a waste of time and money? Have you found it easier just to do your thing and not worry about that stuff and still get pregnant? 
I have a regular MP. It last 7 days. I have a 26 day cycle. 
This is month 1 of trying and CD26 for us.
