Spotting can be a sign of implantation bleeding it usually occurs right around the time you would get a period just before anyways and can cause some abdominal pain as well. Usually implantation bleeding occurs 6-12 days after ovulation. A sore throat and achy bod sounds like your coming down with a cold.....either way get plenty of rest, fluids, vitamins and eat healthy! Good luck to you I hope you are indeed pregnant!
pregnancy symptoms usually are the same as pre-period symptoms. If you know when you ovulated and you know the day af should arrive...test on that day. then you will know for sure. :)
