My girl friend had menses Apr 21~27th, and we had sex May 1th. Since condom was broken, she took Plan B next day and bled May 7~13th. She said it didn't look like a normal, so we were not sure it was a real menses or not. Her period had been very regular, 30~31 days, but she still has no menses. Pregnancy test at June 4th and 8th said negative, but it is so scary having no menses yet. Is she pregnant or just having a side effect of Plan B? Please give us some idea.

Thanks,
