Does Your Ovulation Cycle Change If Your Period Starts Early?

Many women who are trying to conceive hope that they have regular and predictable menstruation and ovulation cycles.  The idea behind this is that regular menstrual cycles make ovulation easier to predict and therefore conception is theoretically easier to achieve.  If you know when you ovulate each month, then it is easier to have intercourse at the appropriate time so that you can become pregnant.  If you want a certain gender, this becomes even more important because you have a higher chance of getting a boy or girl at certain points around your ovulation.  Many people gauge ovulation by using their period as sort of a yard stick.  Many just count 14 to 15 days after their menstrual period and assume that they will ovulate around that time,  which is midway through when they bled last until the end of their cycle.  However, some of these same women might find that their period starts earlier or later than normal.  This leaves them wondering if their ovulation cycle is also going to change also.

Someone might say, “I normally have my period every 28 days or so.  This is the first month that I want to try to become pregnant, so I was going to try having sex around day 14.  However, for whatever reason, this month my period started on day 26.  So my period is actually 2 days early.   Does this mean that my ovulation is going to come 2 days early also?”

That is really up in the air for two reasons.  So many things can affect when your period comes (diet, medications, stress, hormonal fluctuations.)  The same is true of your ovulation day.  Many women do not realize that their ovulation can fluctuate because, unlike the blood that comes with your period, there aren’t as many physical signs that you can see for ovulation.  Many women are actually shocked to find that their ovulation can actually either fluctuate or not happen when they assumed that it did.  I too assumed that my ovulation happened around two weeks after my period.  But when I was unsuccessful at getting pregnant in a reasonable period of time, I started testing myself with urine and saliva ovulation testers (like these on Ebay.)  I found out that I DID NOT ovulate around day 14.  Instead, I ovulated anywhere from day 18 to day 20.  It actually fluctuated, even though my periods was mostly regular.  Since knowing when you ovulate is so key in becoming pregnant (and in choosing your baby’s gender if you care about that) then why guess?  Ovulation predictors are inexpensive.  Use one to test yourself so that you will know for sure.  Your ovulation may not have been happening on day 14 and it may or may not come two days earlier because of your early period.  Testing is the only way to be sure and it is very easy and inexpensive to test.
