Could someone tell me the difference between the two? I always hear horror stories of women who thought they had their period during pregnancy, but were actually just having vaginal bleeding. I had unprotected sex last month--took Plan B--had a Plan B induced period (when it was normally due) and have recently began this month's period today (as expected). I know the chances of pregnancy are slim, but could someone tell me the difference. Google doesn't seem to know the answer to this one.
Thanks in advance.
