I dint know but I was taking a blood pressure pill and a water pill I.stopped mine I'm 4w3d and I have an appointment on Friday . I will ask for a test also some preg safe BP.pills
they usually advise against tking any kind of herbal supplement although i dont know how cinnamon could be a problem but you never know. You can call and ask any pharmacist they will tell you if its okay or not. I took echinacea everyday until I became pregnant and the dr told me to stop
I would call and ask the nurse at the doc office or the pharmacists but if its to keep your sugar level there's probably more danger of going off it for only a week to find out its safe I would wait or call in to the doc!
