hello I’m dr. Sapna hula practicing consultant obstetrician and gynaecologist practicing presently at motherhood hospital HR BR it is a common belief that a woman cannot become pregnant after intercourse with her partner during menstruation however there are exceptions to this rule this implies to those individuals who have irregular periods or shorter cycles so now you are asking the question how can this happen and in such cases sex during periods could lead to a chance of 1 percent of pregnancies so there you are now wondering how can this actually happen for example if your cycle is only about 21 to 24 days you could have a premature ovale ation with the sperms still inside you for a good three to five days the sperm can have its date with the egg the chances of such a date leading on to pregnancies are only about 1% so do you actually need an emergency contraceptive pill otherwise a hormonal pill to prevent such 1% of pregnancies my recommendation would be a No the reason being emergency contraceptive pills are hormonal pills these pills will cause an alteration in your uterine endometrium and also lead to mood swings in you to avoid 1% of such pregnancies I do not recommend an emergency contraceptive pill to be taken after a contact during your menstrual periods.
