So sorry you are going through this. My 1st MC, at 11 weeks needed medical management. It was the most painful of all my mc's, due to the meds causing contractions, but manageable. All I had was paracetamol. The acute pain stage was only when the cervix was opening, so less than 1hr.
2nd was at 7 weeks. I had spotting, but no pain at all, so went to work. Unfortunately I mc's at work! Bled for about 6 days, and was very similar to a very heavy period. My next period started exactly on time a month later!
3rd MC at 9 weeks, was more painful that the 2nd one, but not as bad as the one requiring medical management. Once again I had some period like, mild cramping, but the acute pain that time was only maybe 15mins.
I found walking around and being active helped to open the cervix and move things along. It was the normal side effects of the medical management pills which were the issue. Its very common to get nausea, vomiting and diarrhoea. You can also get a fever. My face went like a beetroot and I was burning up! Paracetamol helped the fever too, but I wished I'd be told about the side effects beforehand, then I might have known what was going on!
Personally, in your case, I'd wait and see. Don't be worried about the pills though, if that is what is advised down the line. The link below might be useful too. They also have a live, helpline if you need to talk to someone.
