Just another confusing ovulation question:

Sherri • With the help of Glow, now pregnant with my third and final baby! :)
​As you can see I've been ovulating since the 12th. First of all is that normal? I thought the were only supposed to last a couple days? But my MAIN question is that Glow said my fertile period ended on the 13th. Which is clearly not right. And the past few days I've felt very crampy and wet almost like I'm constantly "open". And the wetness is really like you're ready to physically accept your man. (Sorry if TMI) And lastly as long as you have a "surge" you still have a shot in pregnancy right? Sorry for the longness of this I'm just soooo confused!! Thanks in advance!!
