I had unprotected sex July 29th and took plan b the next morning, then had unprotected sex the following night. I'm due to get my period very soon, within this week, but the problem is that I had unprotected sex again last night and I don't know whether to take plan b again or not. I don't know if my period coming soon (at least it should) would effect my chances of getting pregnant in any way, along with the plan b being in my system recently. Thanks in advance.
