Trying to figure out my EDD.

I usually track everything so closely when TTC. This cycle was super weird though! Of course I forgot to mark the start and end of my last period, so I had to guess when logging that (but I think I got close). I marked the times we had sex (the 11th and 14th). I got a positive opk on the 11th, but then on the 14th started to have what appeared to be ovulation spotting? Which I have never had. So we tried again. The app predicts I ovulated the 13th. My EDD is somewhere between February 1-4. Haha. I know it’s not a huge deal, and I will probably request a dating sonogram at my first appointment. I just had everything tracked so accurately and could pinpoint my due date last time. Sigh.
