._. by your description im.. 88% sure you are pregnant..
girl.. go to your doctor fast.. if it has past 8 months your baby might be at risk..
if you aren't pregnant!! dont F** have sex like that no more.. and its probably that you have an irregular period..
but now go run to your nearest store and buy a pregnancy test.. you should have tested that like three months ago.. god!!
wasting you time asking this.. -.-.
