I had a shortned cycle this. Mine usually last around 6 or 7 days but I was basically off of it 4-5 days after I started. I started the 27th of July and was basically off by the 31st. I had sex the 1st of August (completely off, no blood AT ALL the entire day) and the condom broke. We didn't realize what had happened til after we were done and he had taken it off and checked it. I didn't have any duches (I think that's how that is spelled) so I isn't have anything to clean myself out with. After sex, I was bleeding a little and I didn't have any pads to use so I had to use a tampon to keep from bleeding on myself. I was supposed to start my birth control the 2nd but because of what happened the night before I have decided to wait until next month to start it. What's the possibility that I'm pregnant?
