so i have found myself in a similar situation....and while searching the web for others going through the same thing i found this thread.........i am 3 weeks late my last period was september 8th give or a take a day...and i was expecting my last on the 6th of Oct...but still not here....i have taken 3 tests all negative ...today being my latest... i had been on birth control for 7 years ...until last march when i decided to stop...have switched to just condoms which has been working well....for the most part...my partner and i do have unprotected sex from time to time....where he always pulls out....which i realize is not fool proof ...so theres a definite possibility that i could be pregnant. my cycles have been a little longer since i stopped taking bc. they were 28..and now they are around 30/31 days ...but never 3 weeks late. i have been keeping a mental log of weird things happening...on 0ct 18 ...cycle day 40 i had major cramping and was constantly visiting the restroom because i kept thinking af was there...but nothing. i feel sensations of tugging in my abdomen and oct 19 i was in the worst mood i have been ever just super annoyed and bursting into tears for no reason. ...was assuming my af was coming....i was thinking this could be because i'm no longer on bc but i've been off for 7 months and my cycle has been pretty consistant since i've stopped........anyway its all really confusing and i just hope i get my AF or a + test so that i can set my mind at ease. keep me posted on your events and i'll try to do the same.
