pregnant?

[xolexinicole]

My periods are regular, they come on the 14th or around.
but last month it came on the 25th. It was a lot heavier, darker, and lasted atleast a day or two longer.
me and my ex had sex about 4 times on the few days before it came & once the day i got my period, with no protection which i know wasn't safe.
I'm still having symptoms tho, i've been really gassy, dizzy, tired or not being able to sleep at all, i had a headache for three days in a row, cramps, my breasts are sore but off and on -- usually when i wake up, bloating, and back pains. i've been kind of emotional, i haven't really felt the need to pee more often or been any hungrier than usual.
I don't know if it's possible i might be pregnant, or what's going on with my body?

Your fertile time is about 14 days before your period starts. Did you have unprotected sex between the start of the month and the 11th/12th? If you've had a very heavy period I would think you probably are not pregnant.
