Hello,
Thanks posting your query,
Your current presenting symptoms it seems you are having a
threatened miscarriage and will require urgent attention from your DR.
The current statistics for
pregnancy loss with a SCH is 1-3%. This low percentage is related to large clots. Most pregnancies progress with no further complications. Most clots resolve on their own by 20 weeks of pregnancy. The clot either bleeds itself out or the body absorbs it.
There is no known cause for a SCH but many researchers speculate that during egg
implantation, the egg slightly separates or tears from the uterus causing a bleed. There is nothing a woman did or could have done to cause or prevent them. SCH occurs to pregnant women of all ages and races.
You might still require treatment with
progesterone or estrogene and maybe additional medications such as
aspirin, lovenox etc in an attempt to try to dissolve the clots (Note that there is no definitive treatment).
Hope this helps and wish you the best
