Hello Jade Lewis,
Thanks for posting on HCM,
Mild bleeding during pregnancy
could not be problematic but should be considered serious condition until proven order wise by a doctor. It could be early/actual warning signs of a spontaneous abortion
in progress or a ruptured ectopic pregnancy which in either case will require urgent medical attention.
You will need to see your doctor/a gynobs as soon as possible who can do a quick physical examination (including a vaginal exams), run maybe a pelvic ultrasound
(to evaluate the state of embryo) and provide you with appropriate medical care. Your situation should be considered urgent.
Hope this helps in time.
