My husband and I had intercourse on Friday. We skipped Saturday as I was out of town. My ovulation tester (First Response Early Ovulation Indicator) turned up "yes" on Sunday, but we didn't get around to being together. We also have not *yet* been together today. Have I missed my window for this month? (The kit said to have intercourse within 24-36 hours.) Or, could I become pregnant from Friday's adventures? I have ready that sperm can live for up to three-four days in the female body.
