Stressed and losing hope

Kayla • Had a miscarriage in April of 2020 at 12 weeks 😔 Baby Grayson due November 2022 💙🌈

So me and my fiancé have been trying for our rainbow baby for a pretty short time ( about 3 months ) and I got my hopes up this month because I’m on cd 39 and .... no period and no BFP . Now I’m starting to stress thinking something is wrong with me ( and I have irregular periods but they aren’t too bad) . I’m already losing hope .. ANY TIPS TO MANAGE STRESS
