I highly doubt you're pregnant.
First...
your bf doesn't have to come inside you to get you pregnant, pre-seminal fluid can contain enough sperm to do that... so be careful, a broken condom is never a good thing if you are not prepared to have a baby or fear for STDs.
Second...
Menstruation stops if you are pregnant (except in some extremely rare cases) what you feel could be a side effect of the pill you're taking.
Finally...
If you wanna be sure... get tested, but I don't think you are pregnant.
i stopped having sex at the middle of the period cycle, say 4 weeks every cycle, i have sex without a condom 7 days after period and 7 days before period is due. condom is on every other time... as to my information given, its is impossible to fall pregnant so close to your period. but i want you to google this as the days may be slightly different..
but thats what i do anyway, no contraceptive at all no side affects, nothing.. just no sex during the centre of the cycle....easy.. and no pregnancy. we have 2 kids that we wanted, and no suprises.
i think your bit nuts having sex with just a condom and without contraceptive, if you dont really want to fall pregnant...
theres nothing more greater feeling to a guy than to come in their partner...find out this information about the timing of the cycle. it will be definately a benefit to you.

The cramps could very well be side effects from the ECP. The ECPs deliver a very potent dose of hormones to ensure that pregnancy does not happen (which is why it's recommended as a backup form of birth control - it's very hard on your body). How long has it been since you stopped taking the pill? The cramps and irregular bleeding could also be a side effect from that - as your body adjusts to a new schedule of hormones (instead of a pill-regulated dictated schedule).
Try a home pregnancy test if you're still paranoid about being pregnant, and wait to see if any other symptoms develop. "Implantation cramping" sounds like a myth to scare people about pregnancy (to me, anyways, but I haven't been pregnant) - anyone feel free to demonstrate otherwise.
