We had sex 13 days before her period. We had unprotected sex about 8 days straight, twice per day. I didn't shoot inside her. Her period was delayed 5 days in the first month, and period lasted about 2-3 days. A week later (This is between 3rd and 4th week), she keeps making "Jokes" to tease me that she getting a headache and the feeling of vomit. I've notice she also sleeps a lot too. I have a feeling she might actually ovulating. I've told her before I do not want a kid yet, but if it does comes down to it, I will take full responsibility as her loving husband and the love of our child. Could she still be pregnant after delayed period??
