Hello, Welcome to HCM, I am Dr. Das
Look, nasbandhi operation is done by blocking or cutting the spermatic cord
. By this method, sperm is not ejaculated. Only the seminal fluid is ejaculated.
So, she did not have to take the pill.
But, the symptoms you described are indicative of side effects of the pill.
Just wait for normal period. After that there will be no problem.
