Progesterone suppositories bleeding!?

I just started progesterone suppositories three days ago I am 5weeks and some days pregnant. I had some bleeding after the first day then nothing the next day. Last night was my third time inserting one and just now (the next afternoon) I passed what looked like a blood clot! Is this normal!? I had no bleeding before or after just a blood clot came out and that was it! Has anyone experienced this? Trying not to panic as I just had a miscarriage last month. My doc isn’t in until tomorrow.
