Hi, and thanks for your query on 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. It is best to avoid ovulation time to be safe from conceiving. One can calculate the ovulation date (approximate) by subtracting 14 from the average duration of cycle. So in a 28 day cycle the ovulation occurs on 14th day from start of menses, in a 30 day cycle the ovulation will occur on (30-14=16) 16th day of the cycle. The day is counted from the first day of the period. 3-4 days before this day to 2-3 days after the day is the most fertile period. Having intercourse during this time can result in pregnancy.

Sperm ejaculated inside the vagina can live for 3-5 days to fertilize the egg. Whereas the ovum only lives for about 24 hours in the fallopian tubes and is available for fertilization. Hence, you should avoid having an intercourse 3-4 days before the expected ovulation date to 2-3 days after the expected date (since the time of ovulation can vary by a day). Hope this helps. Take care!

Welcome to e health forum.

If you are persistently having irregular cycles, then it is possible that you are not ovulating and hence chances of pregnancy are very low.

The average menstrual cycle lasts 28 days, but can vary between 24 and 35 days. Menstrual bleeding normally lasts between two and seven days, with the average being five days.

The regular menstrual cycle in a woman is regulated by secretion of hormones from the hypothalamus, pituitary gland and those from the ovary. Any defect in any of these three sites can change the cyclic changes that occur in the ovary and the uterus and hence influence the menstrual flow.

Common causes for a missed or irregular cycles can be - Severe stress and anxiety, acute weight changes, eating disorders (Bulemia), Athletes (Rigorous exercise), conditions like ovarian cysts (with irregular cycles), Hormonal conditions (Eg Dysfunctional uterine bleeding) and hypothyroidism.

If your cause is due to imbalance of hormonal levels , then your doctor will provide you proper medications which will help to regularize your menstrual cycles.

But the treatment in such conditions will be required for a few months and you should be patient and follow your doctor advice.

If you are planning to get pregnant, your doctor will prescribe you ovulation inducing medications which will help you get pregnant.

I hope this helps.
