I think for this kind.. in order to have a peace of mind, it would be better to consult your gynae than to get non professional advice here. Your gynae will check and advise if your condition is normal or what is the next course of action to take note.
For me, I bleed for 12 weeks and I seek medical advice. My gynae told me it’s normal. Checked through and nothing’s wrong. At least I am not worried.
