Another BFN

Me and my husband have been TTC for 7 months. I try not to test every month because I always get my hopes up, so I usually only test when I'm late which has been a few times in the last several months. I have been using glow for about a month faithfully everyday and this month I was so excited to test that I tested 11 dpo and got a BFN. My period is due this Sunday the 23rd and I'm praying it does not come! Every day I see someone else pregnant and I get so emotional and mad, but I know it will happen when it's meant to be.
