Would I feel cramping and bloatedness the day after unprotected sex?

Me and my boyfriend had sex with a condom and then later on in the night, unprotected sex. Chances of pre-cum are likely. I believe I was ovulating at the time even though it was around 1 week before my next period. I took the morning after pill just to be safe the next day. Immediately the day after the unprotected sex, up untill now 1 week later, Ive been feeling crampy nd bloated and increase in appetite, like i usually do right before my period. Is it possible at all that u would feel pregnancy symptoms 24 hours unprotected sex? or is this just my usual period cramps? the only reason im worried is bc my period was due two days ago.
