Abdominal pain

Charlotte • Married just over a year a TTC No 1.
The last day I have had this full abdominal pain below my belly button area it's more prominent in my left area. I have been following the app religiously for the last two weeks and according to the timings I should be ovulating. I was just wondering if anyone else has had this pain. It's too early to do any pregnancy tests. 
​Thank you .
