Hello dear,
I understand your concern.
In my opinion there can be different causes for spotting or
bleeding during pregnancy like:-
1)Hormonal insufficiency like
progesterone insufficiency,thyroid abnormalities etc.
2)Abnormal pregnancy like
miscarriage.
3)Bleeding from cervix .
4)Bleeding due to excess physical strain.
etc.
So once there is spotting or brown discharge all the above causes should be ruled out.
I suggest you to
consult doctor for physical examination and and necessary investigations.
The investigations like thyroid profile,ultrasound might be needed.
Physical examination helps to rule out any bleeding from cervix.
Nothing to worry.It will subside once the cause is treated.
Avoid physical stress and intercourse.
Relax.
Take prenatals.
Hope this helps.
Best regards...Dr.Srilatha
