Hey. I had intercourse with my husband without any protection , I felt that something unusal had happened , therefore to avoid any pregnancy I had taken unwanted 72 a Indian pill to be taken post intercourse upto 72 hrs , but after taking that , I had not got my periods as per regular time and almost 9 days had exceeded as per the schedule but yet nothing had happened . I had gone for a litmus test for pregnancy it is also negative ? Then why ian not attaing my periods ? Iam 34 yrs with 2 child s Nisha Jain
