I do not chart or know when I ovulated, so I was thinking the most accurate thing to do would be to wait 2 weeks since last intercourse and test then? I am trying to apply the 2 week wait rule. Does anyone know if this would result in definitive results? TIA!

Re: When to test?
The intercourse would have only been successful (hence, test-worthy) if you'd done so during **ovulation. If you have a typical cycle (28 days, give or take) you may ovulate mid-cycle, about CD14 or so. But without charting BBT or CM, it's difficult to say. Since you're not sure, I would just wait until the date your period is due and if you do not have it, test. GL
**2 days before and up to ovulation
The "two week wait" applies to people who know when they ovulated based on charting.
If your periods are fairly regular, I would POAS when it is "late" and then test once per week until +HPT or you get your period.
