This is a remedy useful to prevent impending abortion occurring about the third month, ushered in by the appearance of blood, which is oftentimes the first symptom; then follow pain in the small of the back, going around and through the pubes ; there are forcing and dragging pains from the sacrum to the pubes. The flow is bright red and clotted. It is useful for metritis accompanied by flooding from miscarriage. Cinamomum. Useful for abortion from a strain or misstep with profuse haemorrhage and slight pain. Arnica. Threatened miscarriage from traumatism.
For miscarriage in the early months of pregnancy Secale may be the remedy, especially in feeble and cachectic women. It is useful for checking the tendency to miscarriage in the later months, when the muscular tissue of the womb is largely developed. It is indicated by frequent labor-like pains, a copious haemorrhage of black fluid blood, a wan sunken countenance, tingling and formication of the extremities and a desire for air. Hartmann recommended Secale 12.
Its worth a try, hope you are doing okay.
