With my son I pretty sure I know when I ovulated although I wasn't really tracking. We weren't really trying that month as I had just had a miscarriage and had not yet had a regular cycle. We BD'ed about 4-5 days prior to ovulation and I still got pregnant. It was the lucky one as well because it stuck for us! That sperm managed to live 5 days.
The other thing to keep in mind is that you do not ovulate the same time as your LH surge. The average is anywhere from 12-72 hours afterward, with the average being about 36 hours (if I remember correctly). So BDing tonight and tomorrow is a good idea. But honestly, missing one day shouldn't cause any problems and you probably have just as good a chance this cycle as any other. Good luck, hope we are reading about your BFP in a few weeks!!!
You have a great chance. Sperm can live for up to 4 days (I think, please dont qoute me). They say its better to BD every other day so that the quanity of sperm is higher anyways. Best of luck!! Hope you get your BFP soon!!!
And as Rachel said..........STOP beating yourself up:~)
Stop beating yourself up! The good news is you had plenty of sperm ready to meet your egg! That is awesome! The bad news is your beating yourself up so...STOP!!
Good luck I hope this is your month!
