Sad after period

Okay so my boyfriend and I of three years just recently had unprotected sex. We were careless and didn’t really think that having a baby was a big deal because we both love eachother. Well we both started hoping I was pregnant and started think of all the possibilities and come to find out I wake up one day on my period. Since then my boyfriend and I have been a little upset and sad because we’re not having a baby but we know it’s the right decision because we’re both not ready. Has any other couple experienced this?? Like has anyone else feel like they actually suffered a great loss from hoping for a baby but just having a period and no baby instead? And does anyone know what may help us get out of this mood?
