Morning cramping and diarrhea with 15 drops twice daily

well I just completed week 3 of 15 drops 2x a day. Everything was going good and no real side effects untill last week. Each time after my morning dose I would start cramping and I would be in the bathroom with the runs for about 4 hours. My evening dose would be fine and so side effects at all. Today was a little better the cramping wasn’t as bad but I did get the runs for a few hours. I’m going to keep doing 15 drops 2 x a day for one more week. Then I’ll get tested…
