I took plan b 4/17/13 after the condom broke and I am now 9 days late 23 days past ovulation and on cycle day 36 my periods have always been regular and never this late even though this is suppose to delay periods today I had a little spotting that stopped I've taken 4 tests within this 2 weeks 2 may have been early but still came back negative but I feel very pregnant sleep often(always feel tired or lazy) strong food cravings, can't be around certain smells,light headaches,peeing every hour, high bbt temperatures, had cramps day period was suppose to start but it never came sometimes a little crampy and have other symptoms

Idk it could be anything keep going to the doctors every month even if it keeps on saying negative because my mom didn't know till 4 months when it showed positive

The plan B isn't 100% effective, so pregnancy is a possibility. Sadly, we can't diagnose online.

When you tested did you use first morning urine?

Wait another week and test again, first urine of the day. If that test is negative, I'd see a doctor for a blood test, or wait until your next period is due and test again if you miss it as well.
