Heard abt women bleeding during pregnancy being common. should i test if i got 2 periods since incident? both came 10 days late but normal w/ cramps

Can do preg. test: If a woman has a regular normal period after sex, then she is not pregnant. If she cannot be certain that her bleeding was a normal period, then she could possibly be pregnant. A urine pregnancy test (available in stores everywhere) done 3 weeks after the last time she had sex will give the answer. Be sure to read the instructions and do the test correctly.
