Not sure if there is a Question out here like this but i tried to find it before i posted

OK here it goes..
Ron and I been TTC for 9 yrs well we finally got pregnant && we found out on Dec 14 09 then on Dec 22 we lost the baby @ 7 weeks and 6 days.. They are calling it a Blighted ovum..

Well This is how it went they was going to set me a date on Jan 7 when i go to the OB/Gyn .. But i have naturally passed everything It all started on Dec 26 ,27,28 and then on dec 29 i bleed all 4 days then stop bleeding on Dec 30th and 31st.. then spotted on Jan 1st then Nothing on Jan 2 and 3rd.

I have Irregular periods and sometimes they last 2- 5 days..
So i should be starting AF here in the next few days.
My 2 Questions is:
1....Is it possible to get pregnant during a miscarriage or right after a miscarriage has happen?

2.... Do i have a higher risk of having another blighted ovum or another miscarriage?
