According to my gynac, you can physically conceive after one cycle, but waiting for 2-3 months is medically safer to reduce risks. She also emphasized starting folic acid supplements at least a month before trying again.
Doctors usually suggest waiting for 2 to 3 normal menstrual cycles so your uterine lining heals completely. I used my tracker app to log my periods post-miscarriage to know when my cycle became regular again.
I had a miscarriage before my sweet toddler was born, so I know how hard this is. Physically, my doctor told me to wait at least 3 cycles. Take your time, heal your body, and your rainbow baby will come.
Look, don't rush into it just out of pressure. Let your body recover for at least 3 months. Most importantly, make sure you are mentally ready before trying again.
Give your uterus a little vacation first! Medically they say 2-3 months is good, so use this time to eat your favorite foods and pamper yourself. Your body will tell you when it's ready.
