cramping is usual during ovulation, so don't worry. as for the bleeding, how was it? was it heavy? brownish? pinkish? if it was not heavy and not period like, may be pinkish and happened 5-19 days after ovulation, then this might be implantation bleeding and you could be pregnant, but you have to go through the 2WW before testing.
somtimes women can bleed a little after intercourse, but also around time of ovulation some women experience light spotting during ovulation. its normal. but as said above if you started to spot 7 days or more after ovulation it could be implantation bleeding
good luck
