###Human: Why is there heavy bleeding with clots five days after sex? ###Assistant: Hi. The pregnancy test will not show a real result if done before expected next date of menses. Chemical pregnancy bleed or abortion happens only after you miss your period, so do not worry about that. With the kind of bleeding you have (heavy and continuous), implantation bleeding is ruled out. The most probable thing can be an early occurrence of menses or bleeding from the cervical lesion. If it continues beyond a week, you can consult your doctor for examination. If it stops, you can do a home pregnancy test next month if period does not start on the scheduled date to decide further management.
