Hi thanks for your question.
Your last menstrual period was 10th october and accordingly your next due period was Nov 10th.
So your overdue by 25 days.
You have not mentioned the exact date when yor partner introduced finger with sperm.
chances are very less that you will get pregnant by this act of fingering,but since your over due by 25 days ,you need to do home pregnancy
test to rule out or confirm pregnancy. Norethisterone
and has many uses,the commenest beibg the prvention of pregnancy
It has many side effects the commonest being the headache,breakthrough bleeding
,breast tenderness /nd stomach upset
When will you next period occur ,it depends whether your pregnant or not
Hope this answers your question.
