Prog questions

I started prog bout a month ago maybe two but have taken it orally. I’m going off spiro soon so this week I started dissolving my estrogen in my gums (can’t stand sublingual) and using my prog as a suppository. So question is how far should I stick it in and is it supposed to give me the runs? I’ve had concerns the last two days. When I insert it I stop where I get resistance and this before bed so it’s usually gone in the morning as far as I know. The morning after I have to go but I don’t know if it’s a coincidence or a side effect of it.
