Hello and welcome to eHealth Forum!

The last 14 days of a cycle are fixed, that is after ovulation, if a woman does not conceive, she bleeds after 14 days. Since your periods are irregular, you need to sit down and mark the date on calendar each month and see, what the variation is. Subtract 14 from the number of days after which the period comes. Say if your period came on 4th of a month, then counting back 14 days the ovulation occurred on 22nd (May)or 23rd (June)of the previous month.

In August you had period on 6th, then counting back 14 days the ovulation occurred on 24th of previous month (July). In Sept you had period on 13th, then counting back 14 days the ovulation occurred on 31st of previous month (Aug). So the average ovulation time is around 19th (22nd of June)-26th day (31st of Aug) of the cycle, considering the previous few months. So 3-4 days before to 2-3 days after is the most fertile period. The day is counted from the first day of the period.

A pregnancy test should ideally be taken on the day of the missed period. Since your cycle is so irregular it is difficult to say when you should next expect the period.
Since this is a huge variation in ovulation time, you should ideally consult a gynecologist first and regularize your periods. Hope this helps. Take care!
