Coping with what would have been due date 😭

I had a missed miscarriage in December and after many complications had a d & c in January. My due date would have been July 4th. After a very sad winter and holiday season, I was finally feeling myself again. We have been ttc for 4 months now and with no success and what would have been my due date. I'm starting to feel myself unravel. I guess I just needed to vent, hoping someone would understsnd.
