i lost a baby a couple months ago.

one week ago i had unprotected sex and i thought it was too late in my cycle to get pregnant, but the next morning i woke up and knew in my gut.

i've had incredibly sore breasts for the last week and light spotting on the 5th day, and that feeling of "knowing".

but, the spotting now (second day) seems almost like a normal period. light cramping and blood with a few clots.

does that mean i'm definitely not pregnant? or can spotting be that way?
my breasts are still sore and they have NEVER been that way before, on my period or anything.

what's going on?

please help!
