The day after my period ended I had unprotected sex. I took the emergency contraceptive pill about an hour later, and about a week later I bled for 6 days - the usual length of my period. However, it was much lighter than a normal period.
According to my normal menstrual cycle my period is now 4 days overdue - I have always been regular. I don't know whether I should just wait it out to see if the pill's changed my cycle, or to consider a pregnancy test.
I have taken the morning after pill once before and had no side effects, and my next period was on time.
Please help!!

Women taking EC will normally experience withdrawal bleeding about 7 days later. So the bleeding you had 6 days later is typical of withdrawal bleeding. If you are on a birth control pill, this is likely what your periods will be like.

Once you have withdrawal bleeding, it is anybody's guess what will happen with your cycle. It will often be delayed due to the hormonal shock on your system from the high dose EC pill.

Only a pregnancy test can show if you are pregnant. Use an early detection kit like First Response (not the digital one). Use the second stick in the box 7 days later to confirm the results.

Best of luck!
