Second experience with misoprostol but different instructions?

Tomorrow morning I’m taking the misoprostol to start the process of our second mc . This is my second experience with the pills as I had to use them for my first mc, but a different doctor prescribed them this time since my doctor was out of office and for some reason prescribed way more than last time. I’m at the exact same stage in my pregnancy as I was last time but I don’t know that I want to go by her instructions.

First time I did 2 tablets vaginally and repeated in 12 hours. This time I’m told 4 tablets orally and then if that doesn’t work I have to call in for a refill.

I’m thinking I’m going to just do what I did last time because it worked like a charm and I don’t want to use more than I need (I can only imagine it would make it more painful and violent).

Ugh, why is there not a standard method of dosing? I weigh the same, I’m the same amount of weeks, baby stopped at the same amount of weeks - nothing has changed so why wouldn’t I receive the same instructions as last time?

I would call the office but they are closed and this isn’t really considered an emergency.
