I say No. BIG EN OH, So NO. A woman who has just had a miscarriage will have two or three days of having small bleed, until it gets like small spot. The way like when a woman has her period. Pscycologically, a woman who has just lost a baby will be in grief. It takes a bit a while before she is ready to have sex intercourse. How could she be pregnant in a week after that? I can tell this because I once had miscarriage in my second pregnancy. So hell NO.
hardly possible a week after, since an ova needs to be created and that will take at least a month since your body is re adjusting....
but anything can happen, you can never be 100% with this sorta stuff
I cross refrenced a couple of sites form medical to blogs and numerous ppl say that they have become pregnant 1-2 weeks after a miscarriage. so yes
It is less likely, but it is...absolutely...possible.
