Pregnancy symptoms during conception

Me and my boyfriend had un protecteds sex the 29th and my period is scheduled to come one the 4th of next month, so Im pretty much nearing the end of my cycle and im certainly not ovulating..right?
Anyway, its now two days later, the 31st and im having swollen boobs,cramping, and i rolled over this morning and hoped out of bed like always and threw up a little.
Ussually people have 'pregnancy like' symtoms (symptoms) after a week. Cold it be that im possible that i am pregnant and showing symptoms this early ( Just after twol days!) , or that these are the early symptoms of my period about to come on.

I was sort of experiencing this but af isn't supposed to come till the 11th. I felt queasy 2 days after my husband and I had sex and have had sore nips ever since then too. We had sex on the 26th though. I really wish I could be more of a help.
