Disappointed after BFN this morning :(

Caroline • engaged to the love of my life. We've been together for 10 years, baby number #1 on the way, due 25th August 2016 ❣❣❣
Took my second test this morning, first test was done on Saturday and both were negative. Due my period in two days but I have been having cramps, sore breasts, fatigue for the last three weeks so I thought I was pregnant but sadly I don't think I am :(
