heeelllppppp

okk well
i have been on the pill for the last two months now
and since then it seems that everytime my boyfriend fingers me.. i started to bleed... sometimes little sometimes a lot
he doesnt really caree so he keeps doin it anways and it stops... its only at the beginning that i bleed but it is everytimeeee
we though maybe it was a scratch he keeps opening everytime but we never did anythinig for about 5 days and even then it happened ... but the weird thing is if he doesnt finger me ... and we just have sex... then i dont bleed
so i am just wondering whhhatt is goin on
cuz its really annoying bleeding everytimee
is the becuase of the pill... or something else
please helpp
thanks
