Thanks for the query.
Pulsating sensation could be aortic pulsations.
Since you are on oral contraceptive pills
, less likely you are pregnant.
You can expect your period in a day or two. Even after 1 week if you dont get your periods, consult a Gynecologist to narrow down the causes of delayed periods like thyroid
problem, stress, hormonal
imbalance, ovarian cyst
Hope this helps. regards,
