The average menstrual cycle is 28 days - but everyone is different, for some women their menstrual cycles may be 34 days, it is also normal for menstrual cycles to differ by up to a week from each other.
Usually ended, but everyone's cycle is different so it may be more days than that.
Roughly April 26th.... If you have a normal 28 day cycle.
Typically a dog's period cycle will last for 21 days.
its just irregular, this is normal for the first years, up to 3 or even 4 years until your period cycle will become normal.
Usually the date of conception is about 2 weeks after your last period, or in the middle of your cycle. This is when your body ovulates.

If you mean that your last period started on the third then the next one would be due on the 29th IF it remains at a 26 day cycle. Cycles are not always exactly the same from month to month. Start counting the days from the first day of your period. Don't include the first day of the next one when it comes as that is day 1 of your next cycle.
Any counting of days regarding menstruation or fertility is always from the first day of your period - LMP is the day you started your last period, fertility window is from LMP - to days 9 thru 16 - the average cycle is 28 to 34 days beginning with LMP.
Somewhere between July 2 and July 6, depending on the length of your cycle.
July6

Take a pregnancy test Peak fetilization is day 14 from the first day of your last period. You are in the window.
