Is there something I could do now?

My period had just ended saturday two weeks ago and I had unprotected sex on sunday, monday took plan B. Next friday my period came back.. That following saturday I had sex with condon (while being on my period) after an hour we had sex again with no condom and my bf pulled out, but he had came that same hour before.. Any risks??? I didn't want to take the pill because I had already done that a week ago ...
