Misoprostal not working????

I had a misscaraige 3 weeks ago, spontaneous, a lot of blood loss and clots. This week my hcg went up slightly from already going down 14,000 points, so the dr gave me cylotec to start the process over again. Well its been 12 hours and I've barely bled at all. Just spotting pretty much all day and some mild cramps. So wtf! Anyone experience this??? I'm thinking its not working? It must have worked some because I wasn't bleeding prior to this bit I'm expecting ALOT of bleeding, and was told by the second dose id feel like I was in labor.... Well I've had all 4 doses already and I feel fine. 😒
