Cyst or ectopic?

I have a history of ovarian cysts, however I have not had any in 4 months, and in the past I only ever had them on my right ovary. 
ANYWAYS- so I am about 8 dpo and I have been feeling really off the past few days. And I have been cramping ever since my o day. 
I woke up this morning and all day I've been having on and off sharp pains on my left side. Similar pain to my cysts but they're actually a little different. 
Any opinions on what you ladies have felt in the past if you have had a similar situation? What was the outcome? 
PS: I will be calling my doctor in the AM if it doesn't go away
