I tested first with a Walmart cheapie, then held my urine for four hours and tested with the first response. The OPK was just for kicks. 
I got pregnant my first month trying with my daughter (now 11 months old) and this is our first month trying for #2 after breast feeding for 8 months. I had only gotten my period back for two cycles before we tried last month. My husband and I are so excited, and hoping it's a boy! 
I should be due in August 2017 and my daughter would be 19 months old! 💕
