Can Intake Of Nordette Help In Delaying Menstrual Periods?

Hello Doctors! I just wanted to ask. I took nordette as an ecp last week after a deed. However, I only took 2 pills at the start because I asked helped from a friend and that s what she told me to do.. after, I searched the internet and it said to take 4 pills and after 12hrs, another 4 pills. So after 12 hrs, I took 4 pills again. I took a total of 6 pills.. because after the last 4 pills I took, my system wasn t able to handle it and I vomitted. I was past my ovulation period when the deed happened and my period was due yesterday but until now, i still don t have it. Can nordette delay your period? It s been a week since I ve taken nordette.
