I had sex pretty much the day I came of my period . And the condom split but we only noticed half an hour in and then stopped . But he did not ejaculate I am aware you can get pregnant from pre come but as I was only just off could this be possible. Since then I have ad brown discharge and minor stomach cramps and headache and felt a little tierd and feel bloated . I don't know if this is in my head or not . I'm not due on until 10 days so can't really do a test ? Help??

Generally pregnancy occurs if you have sex during 10-18 day after your periods since 14th day is assumed to be the day of ovulation.
But at other days you are generally safe to have it.
So since you had sex soon after your periods, you might be safe because there is no egg to receive sperm !
You can have a sigh of relief.

Women have gotten pregnant while on their period, so really, unless you know for sure when you ovulate, it is possible to get pregnant right after, right before, or any time in between your period.

The above poster is posting what the average female experiences. There's no way to know if you fall into the average category.

Wait until your period is due. If you miss it, wait a week or two and then test using first morning urine. If that test is negative then wait until your next period is due, and if you miss it test again or see a doctor for a more accurate blood test.
