I had my last normal period March 14th. I had unprotected sex March 24th for 5 minutes before the man ejaculated. He did not ejaculate at all. I took plan b an hour after the incident happened. I began bleeding for three days March 30th and it was fairly heavy. My periods are fairly irregular; they come every month, but come different days (I.e. 23-33 days) .I was suppose to get my period a week ago. I was wondering when I should expect my period and did the plan b work my stopping my ovulation? Will I get my period in 2 weeks?
