I was having sex during my fertile days when the condom broke. I took Next Choice around 65 hours later. I took the pills together since it had already been so long. Today which is 9 days after sex and 6 days after taking next choice, I noticed a very small amount of brown discharge when i went to the bathroom. Now it's completely gone. Was this more likely from next choice or am I likely pregnant and experincing implantation?

Please Help! I'm really worried.
