Avoiding Miscarriage at 41

I am 41, fit, and healthy. I have 6 children ages 17 to 2 - all fine and healthy. My pregnancies resulted in infants all over 9lbs and one 10lbs. I have had 2 miscarriages in the past 10 months at 10 weeks and 16 weeks, the last one with massive blood loss with tranfusions. My periods are just settling now, and I'm ovulating, although my periods are ending with a few days of brown staining. Is it possible that I will have a full term pregnancy? Thanks for your time.
