ive had sex four times this month..after the first time (july 2) i took the plan b pill. i then got my period about 5 days before i normally do. i had sex again on the second day of my period (jul 16). about aweek laterr (july 23, period was over) i had sex and took the plan b pill again. that week (july 25) i got my period again. july 30 it was still my period but i had sex one more time. each time i had sex my partner pulled out, he just insisted on getting the pill.. and normally my period is pretty regular, getting it around the 20th every month. but since i took plan b twice this month which im assuming is why i got my period twice this month, should i expect my period in august ? will it be later than normal? also, just out of curiosity, is it actually possible to ovulate while on your period ?
