Sharp pain had previous ectopic

Laura
So I'm 10dpo and got a negative pregnancy test this morning. I have been getting an almost stitch like pain in my tummy are since Saturday and now tonight I'm getting a short, sharp, stabbing pain in what I can only describe as the right side of my womb /ovary kind of area! 
I'm praying it's just AF symptoms and not the start of an ectopic, any thoughts? 😢
