Meds, miscarriage, and moving on?!

Found out last Friday that I officially miscarried (blighted ovum) sac measured 5w2d. By Sunday I started some bleeding, picked up a little more on Monday. Ended up taking Misotropol (sp?!) on Tuesday because my numbers were barely decreasing (4100 to 3400.) Anyone take those meds? How long did you bleed? Dr said we could start trying again immediately. This would have been my 3rd pregnancy (we have a 5 & 1 year old.) Just wondering how long I should expect this to go on...ready to move on and try again!! TIA
