Ovulation??

Mishila
I have Nexplanon in my arm but planning on getting it taken out the 23rd so we can start trying. But for the past couple days i've been having cramping on my lower right side. I had an ectopic pregnancy March 2015 and lost my left tube due to it rupturing...the pain feels similar but mild in comparison. What do you think it could be? I'm feeling it right now as i type this. Oh also I'm still getting my period so ive been logging it glow says I'm supposed to ovulate today.
