Okay first of all sorry I'm not a woman as this site is for women so my gf and I had sex as usual on Christmas night around 9pm. the condom broke and my penis went straight through the hole and we didn't know until i finished inside her. Before 11pm she had already taken Plan B. Her first day of her last period was 12/11/16 so she was likely ovulating. She had no side effects and now 1/9/17 which is when she is due for her period she is experiencing light bleeding and heavy cramps (she usually has a heavy period). Is this due to plan b effecting her period or is it implantation bleeding? When should i test her for pregnancy?

Maryann, thank you again for the response, she bled for 5 days and it was a flow but she usually bleeds for 7. Are you sure it's still her period?

Hello chrisfernandez989,

All that I am sure of is that this is not implantation bleeding. You mention that the bleeding started at the same time her period was due.

Regardless, the bleeding is proof that she is not pregnant.

Maryann, thank you for the quick reply and warm welcome, this is now her third day of bleeding and it has progressed from spotting to a red flow of blood but still not her normal amount and it has been 15-16 days since possible conception. So is it likely not implantation bleeding?

Hello chrisfernandez989,

This bleeding is not implantation bleeding but bleeding caused by taking the emergency contraceptive pill.

Hello chrisfernandez989,

Welcome to the EmpowHER community. We welcome men and women. Thank you for reaching out to us with your question about Plan B and your girlfriend.

Plan B prevents pregnancy by preventing ovulation. So, it is effective if taken before the woman ovulates. It can also cause changes in the menstrual cycle. The next period could start earlier or later than expected. Flow can be lighter or heavier than normal.

Implantation bleeding is pink or brown spotting. It occurs about six to 12 days following conception. It lasts two to three days, never increases to a flow, and goes away on its own.

Watch and see what happens. If this light bleeding is more like a flow and not just spots, it is bleeding caused by taking Plan B. That means she did not become pregnant and no need to test for pregnancy.
