Possibility of being pregnant?

ok, I highly doubt it but I am having sudden symptoms a month after having sex.

swollen and sore breasts and nipples
bloated
weird sensations in abdomen
light cramps here and there
nausea
heartburn
moody

I realize these mostly could be diet and PMS. I don't know if I could possibly be pregnant, even though I bled heavily at the beginning of the month.


Thanks!!
