The sex was un protected and not to mention a day after my period. But I have heard of rare cases where people do get pregnant a day after there period and experience symptos right away! Im already having nausea, spoting, cramping, tiredness, bloating, and back pain

You could become pregnant from the sex right after your period ended if you happen to ovulate early. In the right conditions (just prior to ovulation) sperm can live for a few days, so if you were getting close to ovulation, pregnancy could occur from the sex several days before.

However, it would be very unusual for you to start feeling so many possible symptoms as implantation would not be complete at this point.

You'll have to wait and see how you feel over the next couple of weeks and what happens when your next period is due.

Thanks! Yeah cause I knew feeling symptoms this early is weird but I heard of many people that have! Not to mention I'm having crazy period like cramps.. is that caused byimplantation?

Some women do have some slight cramping at implantation, but most women never notice anything. You may also be getting ready for ovulation... cramping can occur at that time as well for some women. Or, it could just be cramps. Maybe due to an illness you are fighting.

You'll really need to wait and see.
