I had a d&c done on friday last week due to having a missed miscarriage, i was prescribed lennon diclofenac 100mg suppositories, i want to know if i need to complete the use of all of them or if i could stop as i dont have inflammation or pain ?

I say stop: Stop the medication and let's focus on the miscarriage. If you have recurrent miscarriages, when you start actively trying to conceive, start one baby aspirin a day, DHEA 25 mg a day and low dose naltrexone up to the beginning of the 2nd trimester, but educate yourself. Google all of this and check with your doc who knows your history well.
