You still have a good chance! Have you had your progesterone level checked? Low progesterone will cause m/c. I personally have to get on a supplement immediately to get my levels up where they should be. I have a couple friends who have had 7 and 8 miscarriages but still had healthy babies. Best wishes to you!!
If you've had a miscarriage before, chances are high but you just have to get into the doctor immediately and let them know about it. But I hope that this one is different for you. A friend of mine has had 4 miscarriages, one right after another and finally she gave birth to a healthy, handsome little boy! Good luck and congrats!
