I had similar experience too, some brown spotting which I thought was my period, but when it come and go on and off i felt very strange and went to TCM to check. At that time I didnt know I'm pregnant till the TCM doctor ask me to go buy the test kit n test. Short summary, I went to see my O&B and in fact I'm pregnant 6 weeks already. Everything is ok, but I have blood clot which is as big as my gestational sac. I had very mix feeling. Doctor said it happened for some women and normal. But for me doctor said I was too active the past few weeks which cause the blood clot. In fact yes, because I did fell down few days before I went to tcm, did a lot of housework and party a lot (year end problem 🤣). Thank God the baby still around..I'm following up with my gynae tomorrow to check the progress but so far my bleeding has stopped. Doctor did gave me some progesterone medicine oral & he did injected me with progesterone as well he said it is faster and better for me to cushion the baby. If oral or from vagina sometimes it doesnt work well, digested and flush out easily. I hope all good for ur case. If any bleeding consistently come out, please check doctor again. For now just rest, dont do anything. Bed rest if possible. I did bed rest 1 week and it really help to speed up the recovery.
