hi! i have been on birthcontrol since april of 2007 and have been sexually active. my boyfriend and i had sex without a condom on November 23rd and i was due for my period on the 28th. i know that this is not 100% effective, but before he climaxed he did pull out. i had my period on the 28th. my period was suppose to end on the third of December, but i was lightly bleeding through out that day and then a real little bit on tuesday. all the while i've had a cold. for the last week and a half i've been tired, emotional and fatigued. i thought this could have been from being sick. could i be pregnant? or could this just be PMS? i am due for another period on the 26th. help please! :-)
