Hi so sorry you are having to go through this.
I had medical management back in October. I have had surgical and natural management previously. I tried to pass all 3 miscarriages naturally but had retained products twice. The first time I had the surgical the most emotionally draining, I felt quite traumatised after it was over, and completely out of control.
The medical management was not as bad as I thought it would be, having read the horror stories. Again I was pushed towards this due to Covid, and I was happy i did this so I could have my partner with me. I took the tablet around 11am. Within 40 minutes I had some cramps, quite mild not enough to need painkillers. By 3pm the bleeding had started, normal first day of period amount. At 5pm, I began to pass clots, it was almost like gushes of blood and clots every 10-15 minutes. I used the super long towels and didn't have flooding, but it was a lot more blood than I had first expected. But it was manageable.
The cramps ramped up, again I didn't need medication. This carried on for 4 hours. Cramping and then gushing. By 9pm it was over, pain stopped and bleeding calmed down to a light period amount. I didn't need any painkillers, I did use hot water bottle and tried to walk as much as I could around the house to let gravity help.
The only thing I noticed with the medical management is that the after bleeding seemed to last forever. Not heavy but spotting for 12 weeks on and off.
Hope this helps. And I hope it all goes well for you.
