So the other day I may or may not have gotten a little bit of sperm on my finger. I washed them but not thoroughly. I only quickly rinsed them. I then dried my hands. About 10 minutes later I walked home and it was a very cold temperature and I was walking for about 3 minutes. I them arrived and went to the bathroom. I am concerned that I could've gotten left over surviving sperm on the toilet paper that I then wiped myself with. later I also had a shower and touched my vagina a lot as I was cleaning it. Could any sperm have been placed in my vagina that way? And one last question, if you get your period, and it arrives late with old blood, does it still mean youre menstruating or is your vagina just releasing what it was meant to several days ago. If that makes sense? Does it make it harder to get pregnant when menstruating? I'm very sorry for sounding so uneducated, but the truth is that I know very little about this category. Thanks in advance!
