Could be alot of things, but it's likely that you ovulated later in your cycle than your usual ovulation time. Which is why using opks are extremely important while ttc, OR maybe you haven't ovulated at all yet.. 14 days is alot to be late.
Well I’ve been having Heartburn and feeling like throw all the time when I eat something but that’s pretty much it for now
I was told by an OB it’s okay to miss a month of your period once in a blue moon. Maybe wait two more weeks then test. I was almost 4 weeks late when I tested.
