Hello dear,i understand your concern.In my opinion spotting or bleeding in pregnancy can be due to miscarriage,ectopic pregnancy,thyroid abnormalities,progesterone insufficiency,cervical bleeding,excess physical strain etc.I suggest you to consult doctor to get an ultrasound done to know the status of pregnancy and thyroid profile to rule out any thyroid abnormalities is also helpful.Dont worry.Take good rest.Avoid physical strain and intercourse.It might subside with apt treatment. Best regards...Dr.Srilatha
