Late period!

Lindsay • Married to a wonderful man! We got married April 4, 2015. We are now TTC #1 and we are super excited and very hopeful!
Hey all! I am a couple of days late and when I tested this evening it was negative. My periods haven't been irregular since high school (6 years ago) they've been very regular since then. Should I wait a few more days and test again or call quits for this month and hope next month I get the two pink lines? Thanks for being awesome ladies! 💜💜
