if my period is on the 6th day of the month and i have unprotected sex on the 21st what is the percentage that i might be pregna

Posted by bee312

i usually get my period on the 6th of every month. i had unprotected sex on the 21st of june. i have gained since then 10 lbs i know it has nothing to do with that but i am thinking i might be late coz of the weight gain. i have been cramping but nothing. i know i am not very late but i am just concerned if i am pregnant. i took a home pregnancy test on the 5th it was negative but it might have been too soon. any suggestions will be greatly appreciated.

if you started flow on 6June then 21June would be your cycle day 16.  If you have the "text book" 28 day cycle" then your fertile window would be cycle days 11-15.


There is a possibility then because of the following:

Looking at May-June cycle you said you began your bleed on the 6th.  Then that cycle ended  5June (your bleed began 6June).

Based on that cycle (assuming a 14 day luteal phase)  you ovulate approx day 16.  The most fertile days of a woman's cycle are three days before, the day of and the day after ovulation.

You say you tested 5July- that would have been approx 14 days past ovulation and at that point the tests are pretty accurate as that is when it generally the best time to test
