Need words of encouragement...ttc

I started this month with a late period...and had every pregnancy symptoms( was pregnant in March and it resulted in a m/c) my body felt the same way it did when I was previously pregnant. My period was over a week late today and I just got my period. I was very hopeful I was pregnant. This journey is so difficult. I heard a lot of people get pregnant so quick after having a miscarriage...I had no luck n my due date for the pregnancy in March is coming up...October 29. I really wanted to be pregnant before then. Everyone around me seems to be pregnant or just had a baby...trying to be happy for them and trying to stay positive for myself but it seems impossible right now.
