Dun get too worry Michelle, u can do nothing about it now, dun
worry, all u need to do now is to stay calm and wait till ur next
period, once the period come, u r certified YOU ARE NOT PREGNANT
.
I once consult a doctor on this too, he said as long as ur period
is there, it's confirm u r not pregnant. But next time, please use
a condom if u r not prepare to have baby yet. Oh ya, not
advertising here, use a Durex, to be more assured.
Meanwhile pray hard and good luck
