If my period lasts typically 3-4 days, how many days after it would be best for conception?
If all other things are normal, it’s not 14 days AFTER the 1st day of your period, but 14 days BEFORE the expected start of your next period. In the case of a 28 day typical period, both numbers happen to be 14. Stated another way, unless there is a problem with progesterone production, your luteal phase (ovulation to AF) should always be about 14 days. So if you have a 30 day cycle, you should ovulate around day 16 rather than day 14. Of course, there can be issues with a short luteal phase, usually caused by a lack of proper progesterone production. Try charting your Basal Body Temp for a few months and see if you can determine if you have a short luteal phase or a standard 14 day luteal phase.
