Got Early Periods After Taking Postinor2. Will This Affect The Normal Cycle In Future?

My last period was on 4th January, i had unprotected sex and took Postinor 2 on 18 January. My period is very regular and it usually come 28 days after the last period. However, this time my period came early on 25 January. I understand that this is caused by Postinor 2. I would like to know will this early period affect my normal menstrual cycle? or will my cycle resume as normal which is 28 days after 25th January? Thank you.

Hi,
Thanks for the query.
Yes, your early onset of periods could be most possibly due to the emergency pill, as these pills can alter the menstrual cycle.

As you interfered with natural cycle it is difficult to say the next expected date of periods. But as you previously had regular periods, possibly this time you may get your menstrual periods 28 days after 25th Jan.
Take care.
