period but no cramps?

hey everyone! i only had sex once this cycle and it was protected with condom plus pull out. and i got my period on the 30th day of the cycle. however my flow was very light for the first 2 days and a little heavy on the 3rd and then it ended but it was enough to appear on a pad. moreover i didn’t HAVE ANY CRAMPS this time. could i be pregnant by any chance?
