I got my last period on 10/19. My boyfriend and I had unprotected sex on 10/22. Without warning, he decided to let me know that he was finished already. I wasn't aware at first that he meant he had already finished in me. My last day of my period was 10/23. On 10/31 I started to spot. It has only happened once either every day or every other day. I'm not due to get my period again until right around the 19th of this month. Could I take a home pregnancy test now and expect a true result or should I wait until the 19th to take the test?
