Hello dear,
I understand your concern.
In my opinion there are many causes for
bleeding during pregnancy like :-
1)Abnormal pregnancy like
miscarriage 2)Hormonal abnormalities like thyroid abnormalities ,
progesterone insufficiency etc.
3)Bleeding from cervix.
etc.
So all the above causes should be ruled out by
ultrasound,thyroid profile and physical examination.
But as the Ultrasound is normal you need not worry as any abnormal pregnancy is ruled out.
Thyroid abnormalities should be ruled out by thyroid profile.
Bleeding from cervix can be diagnosed by physical examination.
So I would like you to
consult doctor to check for the cause of bleeding.
Avoid physical stress and intercourse.
Take prenatals and progesterone supplements.
Don't worry.
Hope this helps.
Best regards...Dr.Srilatha
