thank you, my period isnt due until around dec 12
The odds of being pregnant without intercourse is much lower. Ejaculating on your vagina is risky, but harder for the sperm to get in there. It is possible, but less of a low risk. The plan b pill, if taken on time, is usually really beneficial. You would have had to be ovulating to get pregnant anyway though. But like njeosys said, just use protection from now on. But considering you said it was an accident, i assume you weren't even ready for sex. Things happen, but it's a low risk and now added the plan b, it's a very low risk. I'm sure you're okay. If your period is late, take a test to be sure.
Honestly, you're probably not pregnant. But those pills can screw up your body. I wouldn't recommend doing that again. Use some sort of protection if you don't want a baby.
You should be ok.........
