My period is never late, had sex last night ( he came in me twice).today i spotted and now nothing. my period usually comes today.... advice? or help?

Technically....: You're not really 'late' yet, since the day isn't over, and it would be normal for the period to be off by a few days anyway. The likelihood of you being pregnant---if you're periods are regular, as you say, is very very low, if this is day 27 or 28 or so. You can take a test in 10 days or so, if you're period still hasn't come, but I'll bet that it comes in the next few days. good luck!
