Impossible to tell if you're pregnant. Too early
. You're also not feeling pregnancy
symptoms. At soonest they start a week after ovulation, when implantation occurs. Even then most women won't notice or have them until around 4+ weeks of pregnancy. This is just because the hormone is high enough then to cause symptoms. (usually they peak or get strongest in weeks 6-9) It's probably illness or something you ate. Might even be PMS. It's most definitely not pregnancy though.
