How does implantation work?
Can someone please explain this to me? My BBT chart says that I ovulated and MAY have had an implantation dip/spotting at 7DPO. I don't get that at all. I mean, I guess it's common knowledge, but isn't implantation when the sperm enters the egg? I could be way off, but that's what I have always thought. And if that's the case, how does the sperm live so long after ovulation? I've heard that sperm can only live 5 days or so after BD, so why would it be any different after ovulation? Sorry, still a newbie to this, but trying to get it all figured out. Thanks in advance for any help!
