Most times your supposed to wait at least 6 weeks to have sex again. So I would assume after that. I had a miscarriage and got pregnant with my first living child 3 months later. I would ask your doctor to be safe though.
I got pregnant two weeks after a chemical pregnancy. Im 7w1d :) Gl hun it will happen..
check with your doctor, it depends on what type of miscarriage and how far along. if it is a chemical pregnancy you can try again right away. blighted ovum, once everything has cleared. anything further along, you need to make sure you are fully healed, or after you have a normal period and hormones go back to noral. HCG levels can remain high, which would cause a false positive on a pregnancy test
you also need to be emotionally ready
