Totally unexpected BFP!!! I'm still in shock!

My husband and I started TTC in August 2016. After numerous negative results and a lot of let downs, we stopped actively trying and went back to just doing everyday life. On Friday I realized my period was 4 days late so I took a test on a whim. The top result is the one I took that night and the result showed up almost immediately!! I could not believe it. Took a second test just now in a different brand -- still positive!!! God is good!!!!!!!!!! Calling my OBGYN on Monday 😍
