I had 3 miscarriages last fall, before finally conceiving this one that I am carrying now. The first 2, I m/c naturally, just a heavy period with some cramping, but not intolerable. Although, I think the pain may have been dulled by the emotional pain. The 3rd m/c ended in a d&c after I started hemorrhaging.
Here is my opinion (from both a personal and medical standpoint)........I think the best way is for the body to let it handle itself. It actually can take several weeks (and in rare cases a couple months) to start the m/c. The hormone levels have to get down to 0 before your body can cleanse the uterus. So, just because you don't start bleeding right away, doesn't mean your body won't take care of you. The only reason I had the d&c the last time was for blood loss (I also have a clotting disorder, btw). Don't let that s
care you though.......doesn't happen often AND there is actually a medication that the doctor can give you a script for to have on hand. Then, if you start bleeding heavier (more than 2-3 pads in an hour) you can take this med. It will slow things down for you, without further need for medical intervention. Also, there is actually a risk of hemorrhaging if you HAVE the d&c, so that should not be your deciding factor.
There are pros and cons to either side. So, this is something only YOU can decide. If it is important enough for you emotionally to be "done" with the whole situation faster that you are willing to take the risks of scarring, cervical damage, etc (not a super high risk, but there all the same) ........then, the d&c is for you. If you would rather let your body handle it in its own way and not take those risks unless necessary.......then, you should probably just wait it out. Either way, do what is best for YOU. Take some time for yourself and start the grieving however you do it best. If that means getting back to work, life, etc......do it. But, if that means taking some time off and crying......do that (and don't feel guilty about any of it).
